Question

A car moves in a straight line from rest at t=0 it accelerates with 2m/sec2 What is time and displacement if the velocity is 10m/sec

Answer 1

Answer:

Distance covered by car = 25 m

Explanation:

u = 0 m/s

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

v = 10 m/s

Time (t) taken reach to reach v = 10 m/s

From first law of motion: v = u + at

t = v - u /a

  = 10 /2

  = 5 s

From second law of motion: S = ut + 1/2 a $t^{2}$

S = 0 + 1/2 x 2 x 25

  = 25 m
