Find <br> (a) the speed acquired, (b) th distance travelled. Question from Class 9 Chapter Motion. Apne doubts clear karein ab Whatsapp par bhi. A body starting from rest moves along a string line with a constant acceleration The variation of speed (v) with distance (s) is repressed by the graph.Find (a) the speed acquired, (b) the distance travelled.Since bus starts from rest, Initial velocity = u = 0 m/sAcceleration = a = 0.1 m/s2Time 12 m/s Thus, Speed acquired is 12 m/s (b) Distance Travelled We find Distance travelled by 2nd equation of motion s = ut + 1/2 at2 Putting values s = 0 × 120 + 1/2...The driver then applies the brakes, causing a uniform acceleration of 22.0 m/s2. If the brakes are applied for 3.0 s, (a) how fast is the car going at the end of the braking period, and (b) how far has the car gone?What is the final velocity of the car? pls.The driver then applies the brakes, causing a uniform acceleration of -2.0 m/s2. If the brakes are applied for 3.0 s, determine each of the following. During segment 1, the motocycle starts from rest, has an acceleration of 4.0 m/s^2, and has a displacement of 400 m. Immediately after segment 1...

The driver then applies the brakes, causing a uniform acceleration of -2.0 m/s². if the brakes are applied for 3.0 s, (a) how fast is the car going at the end of the braking period, and (b) how far has the car gone?applies the brakes, causing a uniform acceleration of 2.0 m/s^2 in the negative direction. If the brakes are applied for 3.0 seconds, how fast is the car going at the end of the braking period, and how far has it gone? I did this problem for homework, I just want to make sure my answer and math is right....a distance S with uniform acceleration, then moves uniformly a distance 25 and finally comes to rest after moving further 55 under uniform retardation. 1 answer. A particle starts from rest and has an acceleration of 2 m/s^2 for 10 sec. Alter that, it travels for 30 sec. asked Jan 15, 2019 in Physics...A 3000-lb automobile starts from rest and travels 1200 ft during a performance test. The motion of the automobile is defined by the relation a A wheel starts from rest and rotates with constant angular acceleration to reach an angular speed of 12.0 rad/s in 3.00 s. Find (a) The magnitude of the angular...

Answer: A car starts from rest and travels for 5.0 s with | StudySoup

10) An object started traveling with a velocity 2m/sec moves with an uniform acceleration of 3 m/ . Q:A car accelerates uniformly from rest to 20.0 m/s in 5.6 s along a level stretch of road. Ignoring friction, determine the average power required to accelerate the car if (a) the weight of the car is 9.0...The driver then applies the brakes, causing a uniform acceleration of - 1.7 m/s2. The breaks are applied for 1.60 s. (a) How fast is the car going at the end of the braking period? 4.2 m/s. (b) How far has the car gone from its start?Physics. Two cars start from rest at a red stop light. When the light turns green, both cars accelerate forward. The blue car accelerates uniformly at a car starts from rest , attains a velocity of 36kmph with an acceleration of 0.2m/s^2 travels 9km with this uniform velocity and then comes to halt with...The v - t graph of a car while traveling along a road is shown (solved). Determine the motorcycle's acceleration and position when t = 8 s and t = 12 s. Find more at www.questionsolutions.com Book used: R. C. Hibbeler and K. B. Yap, Mechanics for engineers - dynamics.Given: vi = 0m/s (because it starts from rest).

First shall we compute the gap from rest and sooner than applying the brakes and the velocity on the speedy of applying the brakes:

For distance:

d=Vt+1/2at^2

where V=beginning pace

d=(0)(5)+1/2(1.5)(5)^2

d=18.75 meter

For the velocity at the quick of making use of the brakes:

v=V+at

v=0+(1.5)(5)

v=7.5 m/s

Then the motive force applies the brakes for deceleration of 2.Zero m/s^2 for Three seconds

the final velocity can be

V(final)=v+AT where A= deceleration of 2.Zero m/s^2 and T= time of braking of 3 s

V(ultimate)=7.5+(-2)(3) ---> A is unfavorable as a result of it is deceleration or acceleration at adverse course

due to this fact

V(final)=1.5 m/s

The distance from the instant of braking to the general place will be:

D=vT+1/2AT^2

D=(7.5)(3)+1/2(-2)(3)^2

D=22.5+1/2(-2)(9)

D=22.5-9

D=13.Five m

Therefore the total distance is

total distance=d+D

general distance=18.75+13.5

total distance=32.25 meters
