Question

Body of mass 10 kg moving with a velocity of 1 m/s is acted upon by a force of 50 n for two seconds. The final velocity of the body is a

Answer 1

Answer:

11 m/s

Step-by-step explanation:

the mass of the body is 10kg

the initial velocity of the body with which it is moving is 1 m/s

the force acted is 50 N

we know that

F=ma

=> 50 = 10(a)

=> a = 5 m/s2

now acceleration is (v-u)/t

i.e (v-1)/2= 5

on solving we get 10 = v-1

i.e v = 11 m/s
