Question

body moves at a constant velocity of 10m/s, find its velocity after 5 seconds and its acceleration.

Answer 1

Explanation:

ANSWER

v

i

=10 m/s and v

f

=20 m/s

Acceleration of the body =

5

20−10

m/s

2

a=2 m/s

2

Velocity of the body at t=−3 sec

v=u+at

v=10−2×3

v=4 m/

Answer 2

Answer:

I suppose that accleration is missing.....
