Question

If initial speed of body is zero.After 3second speed will become 3m/s.Find the acceleration?​

Answer 1

Answer:

Explanation:

In x direction, V  x ​  =3m/s

In y direction, V  y =at=1(4)=4m/s.

V  net =  V  x 2 ​  +V  y 2 ​    ​  =  3  2  +4  2  =5m/s

at an angle tan  −1

(4/3) with initial direction of velocity.
