Question

A object of mass 50kg his moving with velocity 4m/s calculate it's linear momentum

Answer 1

Answer:

MARK ME BRAINLIEST

Explanation:

The mass of the object, m = 50 kg

Initial speed of the object, u = 4 m/s

Final speed of the object, v = 8 m/s

1. Initial momentum of the object is given by :

P_i=m\times uP

i

=m×u

P_i=50\ kg\times 4\ m/sP

i

=50 kg×4 m/s

p_i=200\ kg-m/sp

i

=200 kg−m/s

2. Final momentum of the object is given by :

P_f=m\times vP

f

=m×v

P_f=50\ kg\times 8\ m/sP

f

=50 kg×8 m/s

p_f=400\ kg-m/sp

f

=400 kg−m/s

3. The force exerted on the object is given by :

F=m\times aF=m×a

F=m\times \dfrac{v-u}{t}F=m×

t

v−u

F=50\times \dfrac{8-4}{8}F=50×

8

8−4

F = 25 N
