Question

Questions based on all the 3 equations of motion class 9

Answer 1

Answer:

Three Equations of Motion are v = u + at; s = ut + (1/2) at² and v² = u² + 2as and these can be derived with the help of velocity time graphs using definition acceleration.

Answer 2

1st equation:-

calculate initial velocity if final velocity is 68 m s and t is 5 sec and acc is 4 m/s

2nd equation

calculate the displacement if u=0 t-3 a-5
