Question

A force of 500 N is acting on a body of mass m initially it is at rest after time 5 seconds it acquires the final velocity 50m/s. calculate its final momentum.​

Answer 1

Answer:

Correct question: A force of 500 N is acting on a body of mass m initially it is at rest after time 5 seconds it acquires the final velocity 50m/s . calculate it's final momentu

Given:

Force= 500N

time=5 sec

final velocity=50 m/sec

initial velocity = o m/sec

To find:final momentum

F=M×a( M = mass of a object ,a= acceleration of the object)

500 =m×a-------1

V-U/T =a( V- final velocity , U- initial velocity,T -time)

50/5 =a

a=10 m/sec square--------2

from 1

500 =m×a

500=m×10 ( a=10 from2)

m=50kg

final momentum = mV( m-mass of object,V final velocity)

=50×50 =2500kgm/sec

hence the final momentum =2500kgm/sec

ANSWER:2500kgm/sec
