Question

there is a change in velocity observed from 10m/s to 15m/s when a force of 300N is applied on a body. calculate the mass of the body?​

Answer 1

Answer:

60 kg

Explanation:

Given: initial velocity (u)= 10 m/s

final velocity (v)= 15 m/s

force applied (F)= 300 N

time (t)= 1s

Acceleration (a) = (v-u)/t

= 5 m/s^2

Therefore, Force(F) = mass(m) * acceleration (a)

=> m = F/a

=> m= 300/5 kg

=> m= 60 kg (ans)

Answer 2

Answer: f=ma

F=300N

M= find

T=1

U=10

V=15

Slo. F=m(v-u)/t

300=m(15-10)/1

M=300/5

M=60kg
