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=
t
mv−mu
=
6
800−500
=
6
300
=50N

Answer:we know thet
V=u+at
10=5+a5
10-5=5a
5/5=a
a = 1m/s2
Now force = ma
F=100*1
=100 N
