Question

an object of mass 20kg accelerates from the rest to a velocity of 10m/s in 5 seconds. calculate acceleration

Answer 1

Explanation:

m=20kg

v1=0(rest)

v2=10m/s

t = 5s

a= v2-v1

t

a = 10-0

5

a = 2m/s²

Answer 2

Explanation:

m=20 kg

u=0m/s

v=10m/s

t=5s

a=v-u/t

a=10-0/5

a=10/5

a =2m/s^2
