Question

How much momentum will a dub bell of mass 10kg transfer to the floor if it falls from a height of 80m take its downward acceleration to be 10 metre per second square.​

Answer 1

$\huge{\underline{\underline{\mathfrak{Answer}}}}$

Mass of bell is 10kg

height, s=80/100 m = 0.8 m

a = 10m/s

u = 0

Using : v^2 = u^2 + 2as

= 4m/s

Momentum = MV

10kg × 4m/s

= 40kgm/s

Answer 2

Answer:

Mass of bell is 10kg

height, s=80/100 m = 0.8 m

a = 10m/s

u = 0

Using : v^2 = u^2 + 2as

4m/s

Momentum = MV

10kg × 4m/s

40kg m/s
