Question

an object of mass 5 kg is accelerated uniformly from a velocity of 4 meret per second to 8 meter per second in 8 secon calculate intial and the final momentom of the object also find magnitude of the force exerted of the object​

Answer 1

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=

t

mv−mu

=

6

800−500

=

6

300

=50N
