Question

how much momentum will an object of mass 10kg transfer to the floor if it falls from a height of 5m(a=10m/s2)

Answer 1

Velocity when it reaches the ground
= √(2gH)
= √(2 × 10 × 5)
= 10 m/s

Momentum when it touches the floor
= 10kg × 10m/s
= 100 kgm/s

Momentum transferred by 10kg mass to ground is 100 kgm/s

Answer 2

Answer:

Step-by-step explanation:

Velocity when it reaches the ground

= √(2gH)

= √(2 × 10 × 5)

= 10 m/s

Momentum when it touches the floor

= 10kg × 10m/s

= 100 kgm/s

Momentum transferred by 10kg mass to ground is 100 kgm/s
