FORCE=MASS×ACCELERATION
ACCELERATION = (FINAL VELOCITY -INITIAL VELOCITY) / TIME
SO. ACCELERATION IS EQUAL TO
![(12 - 3) \div 1seconds (12 - 3) \div 1seconds](https://tex.z-dn.net/?f=%2812+-+3%29+%5Cdiv+1seconds)
=9m/s
mass=50kg
so, force =50×9
=450N

ANSWER
m=50kg
Given the initial velocity = u = 3 m/s
Final velocity = v = 12 m/s
There for acceleration = v-u =9 m/s
Given mass = 50 kg
We know that,
F =ma subsituting we get,
F= 50 × 9
F= 450N
that's answer
