of 5 m si to 8 m si in 6 s. Calculate the initial and final
momentum of the object. Also, find the magnitude of the force
exerted on the object.

Answer 1

Explanation:

16.

m = 100kg

u = 5m/s

v= 8m/s

t = 6s

initial momentum = P1 = mu

100×5 = 500 kg m/s

Final momentum = P2= mv

100×8 = 800 kg m/s

F = P1-P2/t = 800-500/6 = 300/6 = 50N
