Question

if a stone reaches a velocity of 8m/s speed in 2s starting from rest find the accelaration.​

Answer 1

Answer:

4 ms^-2

Explanation:

initial velocity = 0

time period = 2 s

last velocity = 8 m/s

now,

acceleration = (last velocity - initial velocity) / time

acceleration = (8-0) / 2

acceleration = 4 ms^-2
