Question

an object of mass 5 kg is moving with velocity 4 m per second a constant force of 20 Newton acts on the object what would be its velocity after 3 seconds​

Answer 1

Mass= 5kg

Final velocity , 25ms

initial velocity, 10ms

time taken ,20sec

by using 1st equation of motion

v= u+at

25 = 10 +(a)(20).

15 = 20a

a= 15/20ms2

We know that mass × acceleration

force = 5×3/4 m/s2

15/4N = 3.75N

force applied

hope this will help you

Answer 2

❗❗3.75N is the answer of your question ❗❗
