Question

An object of mass 500kg is accelerated form a velocity 2m/s to 5m/s in 6s calculate the force

Answer 1

Answer:-

mass of the object = 500 kg.

time taken = 6 sec.

initial velocity = 2 m/s.

final velocity = 5 m/s.

initial momentum of the object = 500*2=1000 kg.m/s.

final momentum of the object = 500*5=2500 kg.m/s.

force required = rate of change of momentum / time taken.

force=(2500-1000) / 6

force=1500/6

force= 250 N.

I hope it help u ☺️

☺️☺️mark me as brainliest answer ☺️☺️

Answer 2

Answer:

250 NUTEN

Explanation:

given that-

M= 500kg

u= 2m/s

v= 5m/s

t= 6sec

we know that-

a=v-u/t

a=5-2/6

a=0.5

from nuten second law

F=M.A

F=500×0.5

F=250 NUTEN
