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?

300kgm/s

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
