Question

Two balls of masses in ratio $2:1$ are dropped from the same height. Neglecting air resistance, find the ratio of
i) the time taken for them to reach the ground.
ii) the forces acting on them during motion.
iii) their velocities when they strike the ground.
iv) their acceleration when they strike the ground

Answer 1

m1= m , m2= 2m.

1. they will reach at same time because g don't depend on mass.

2. m2g/m1g= 2:1

3. both have same velocity.

4.both have same , g.
