Answer:
100 N
Explanation:
Force = m × a
= m × v - u/t
= 100 × 10 - 5/5
= 100 × 5/5
= 100N

Answer:
Given ,
m = 100 kg
u = 5 m/s
v = 10 m/s
t = 5 sec
a = v-u / t
= 10 - 5 / 5
= 5/5
= 1 m/s²
Force is given as
F = ma
= 100×1
= 100 N
final momentum is given as ,
P = mv
= 100 × 10
= 1000 kgm/s
initial momentum is given as
P = mu
= 100×5
= 500 kgm/s
