Question

a force of 10 N acts on a 2kg body at the rest for 25s find 1) velocity attained by the body in 25s 2) distant travelled by it and that time 3) Intial and the final Momentum of the body​

Answer 1

Explanation:

Solution: Here, Final velocity v = 20 m/s and initial velocity u = 0 m/s (the body was at rest yo!). Therefore, Time taken t = 10 s. Hence, using the equation v = u +at. Hence the acceleration of the body is 2 m/s2.
