Question

a car starts from rest and acquireb a velocity 50 metre per second in 5 second? what is the acceleration of the car​

Answer 1

Answer:

ANSWER

Given that,

Intial velocity u=0m/s

Final velocity v=54km/h=54×185=15m/s  

Time t=2min=120s

Now, put the value in equation of motion

The acceleration is

  v=u+at

 a=tv−u

 a=12015−0

 a=o.125m/s2

Now, again from equation of motion

The distance is

  s=ut+21at2

 s=0+21×0.125×120×120

 s=900m

Hence, the acceleration is 0.125m/s2 and distance is 900m

Answer 2

Answer:

Data: v=50 m/s, t=5 seconds, a=?

Solution: a=v/t=50/5=10 m/s^2.
