Question

A motorcycle moving with a speed of 5m/s obtains to an acceleration of 0.2 m/s-2 . Calculate the speed of the motorcycle after 10 seconds. Find the distance travelled by it in this time.​

Answer 1

Explanation:

Given-

u=5m/s

a=0.2m/s^2

t=10sec

v=?

s=?

To find v ,we use 1st equation of motion-

v=u+at

v=5+0.2×10

v=5+2

v=7m/s

To find s,we use 3rd equation of motion -

s=ut+1/2at^3

s=5×10+1/2×0.2×10×10

s=50+10

s=60m
