Question

A car is moving along a straight line at 40 m/s undergoes an acceleration of 2m/s². After 10 second it's speed will be. ​

Answer 1

Answer:

Initial velocity = 40 m/s

Acceleration = 2 m/s^2

Time = 10 s

After 10 s it's speed =?

Means in this question we have to find its final velocity

V= u+ at

V= 40+ 2×10 =40+20=60

Final velocity = 60 m/s

After 10 s it's speed will be 60 m/s ans.

Answer 2

Explanation:

u = 40 (v = u+at)

a = 2m/s

t = 10s

v = 40 +2×10 = 60m/s
