Question

Two objects have the same size and shape, but one is much heavier than the other. When they are dropped simultaneously from a tower, they reach the ground at the same time (assuming that there is no air resistance), but the heavier one has a greater

a. speed
b. acceleration
c. none of the above
d. all of these
e. momentum

Answer 1

e. Momentum

Step-by-step explanation:

The two objects free-fall at the same rate of acceleration, thus giving them the same speed when they hit the ground. The heavier object however has more momentum since momentum takes into account both the speed and the mass of the object (p=m*v).

Answer 2

Answer:e

Step-by-step explanation:

Given

Size and Shape of two objects are same but have different mass

When they are dropped suppose from a height of h m

they reach the ground at the same time

velocity with which they reach ground is same because velocity is given by

`v=√(2gh)`

But the momentum possessed by the heavier mass will be greater because Momentum is the Product of mass and velocity.

Velocity is same therefore mass will decide the magnitude of momentum .
