Question

if the object speed up from zero to 15ms by a force of 8N in 2s what is the mass of the object​

Answer 1

Explanation:

initial velocity (u)=0m/s

final velocity (v)=15m/s

time =2sec

hence acceleration = (v-u)/t

= (15-0)/2

=7.5m/s²

mass of a object = net force / acceleration

=8/7.5

= 16/15

=1.06 kg
