Question

A car starts from rest and accelerates uniformly over a time of 5s for a distance 100m determine the acceleration of the car

Answer 1

Answer:

here is your answer

Step-by-step explanation:

initial velocity of car = 0 m/sec      [ car was at rest ]

time                               = 5 sec

displacement                = 100 m

acceleration      =   ?

by second equation of motion  

s = ut + 1/2 at²

100m = o×5 + 1/2 × a × 5²

100m = 1/2 × a × 25

100 × 2  = 25 a

200 × 25   = a

  5000 m/sec² = a

hope it helps you very well

Answer 2

Answer:

Step-by-step explanation:

initial velocity of car = 0m/s

time = 5s

acceleration = ?

by second equation of motion,

s=u+1/2$at^{2}$

100m=0×5+1/2×a×$5^{2}$

100m=1/2×a×25

100m=1×a×25×2

100m=a×50

a×50=100m

a=100/50

a=2$m/s^{2}$.
