PLEASE ANSWER AND EXPLAIN!



A 4.0 kg rock and a 1.0 kg stone fall freely from rest from a height of 100 m. After they fall for 2.0 seconds, the ratio of the rock's speed to the stone's speed is?

a) 1:2
b) 2:1
c) 4:1
d) 1:1

Answer 1

Answer:

d. 1:1

u= 0

v = u + at

v = gt

v doesn't depend on mass.

hence, velocities of both are same.
