Question

A 30 kg TV falls out of a 5 meter high window, reaching a

maximum speed of 10 m/s. What is the TV's momentum just
before it hits the ground?

Answer 1

300kgm/s

Step-by-step explanation:

Given parameters:

Mass of TV = 30kg

Height of building = 5m

Maximum speed = 10m/s

Unknown:

Momentum before it hits the ground = ?

Solution:

Momentum is the quantity of motion a body possess or contains. It is expressed as;

Momentum = mass x velocity

Insert the parameters and solve;

Momentum = 30 x 10

Momentum = 300kgm/s
