Question

if a body moving in a straight line with the speed of 10 m/s and a force at the body its speed change it to 20 m/s in just 2 seconds find the
1:- initial momentum of the body change
2:- momentum of the body
3:-acceleration produced in the body
4:-calculate the magnitude of the force acting on a body ​

Answer 1

Answer:

P=7200

R=15%

T=4.5

I=PTR/100

=7200×4.5×15/100

=4860

Amount=7200+4860

=12060
