Question

an object of mass 100 kg is accelerated uniformly from a velocity of 4 metre per second to 8 metre per second into seconds calculate the initial and final momentum of the object​

Answer 1

Answer:

final velocity = 8 m/s. initial momentum of the object = 100*5=500 kg. m/s. final momentum of the object = 100*8=800 kg.

Answer 2

Step-by-step explanation:

Mass of object, m=100kg;

initial velocity, u=5ms −¹

; final velocity, v=8ms −¹

; time, t=6s

Initial momentum =mu=100×5=500Ns

Final momentum =mv=100×8=800Ns

Force exerted on the object,F= mv−mu/t

= 800−500/6

=300/6

=50N
