- Can the direction of velocity change while experiencing a constant acceleration?
- Can a body having zero velocity still be accelerating?
- A body is projected vertically upwards with a velocity of 20 m/s. Find the distance travelled by it in 3s. Taking g=1om/s

^{2}1-Yes ,the direction of velocity can change while experiencing a constant acceleration. Like, in uniform circular motion there is a change in direction of the velocity and acceleration is constant in this case.

2-Yes, that is certainly possible. If we throw a ball in the air,then at its highest point the velocity is zero but it is still accelerating downwards due to gravity.

3-

Given that:

u = 20 ms^{-1 },g= 10 ms^{-2 }and t= 3 sec

Using equation of motion

s = ut + ½ at^{2}

s= 20×3 – ½×10×3^{2}

= 60 – 45= 15 m
