Question

Mass of 25 kg is at rest force of 100N is applied to it what will be the velocity after 10 sec. what will be the distance covered by the body during the time.... Tell me fastttttttt​

Answer 1

Explanation:

mass(m)= 25kg

force(F)= 100N

Time(t)=10 sec

distance covered(s)=?

acceleration(a)=?

we know, F= ma

100= 25 × a

a= 100÷25= 4 m/s²

initial velocity(u)= 0 m/s

Final velocity(v)=?

By equation of motion

•v=u +at

v=0 + 4×10

v=40m/s

• v²-u²= 2as

40² -0² = 2 × 4 × s

1600= 8s

s= 1600÷8=200 m

Hence: Velocity of object after 10 sec is 40 m/s

Distance covered= 200m
