Question

10. Acar starts from rest with a constant acceleration of 5m/s2 along a straight line .Find the distance travelled by it in the first 2 seconds and the distance travelled by it in the 2nd second.

Answer 1

Explanation:

u=0

a=5m/s^2

t=2s

v=u+at

v=0+5*2

v=10m/s

S=u*t+1/2*a*t^2

S=0+1/2*5*2*2

S=10m

Now, t=4s

S=u*t+1/2*a*t^2

S=0+1/2*5*4*4

S=40m

Therefore, The distance travelled by it in first 2 seconds is 10m and next two seconds is 40m
