Question

An object at rest starts moving. It covers a distance of 2m in one second. It covers further distance of 5 m in 2 sec. In same direction what is avg velocity and acceleration

Answer 1

Answer:

average velocity =2.25m/s

average acceleration =1.125m/^2

Explanation:

velocity =displacement /time

u=2/1=2m/s

v=5/2=2.5m/s

average velocity =(2 +2.5)/2=4.5/2=2. 25m/s

acceleration =v-u/t

a=2-0/1=2m/s^2

a=2.5 -2 /2 =0.5 /2=0.25m/s^2

average acceleration =2+0.25 /2=2. 25/2

1.125m/s^2
