Curling is a sport played with 20 kg stones that slide across an ice surface. Suppose a curling stone sliding at 1.5 m/s strikes another stone and comes to rest in 2.5 ms .Approximately how much force is on the stone during impact. 160N 800N 1600N or 8000N

160N

= 12000 N

Explanation:

Using  the formula, we have:

impulse = chenage in momentum

F*t = mV

where,

m = 20kg

t = 2.5ms

= 2.5 × 10⁻³s

v = 1.5m/s

impulse = chenage in momentum

F*t = mV

F = 20*1.5/(2.5x10^-3)

  = 12000 N

this would be about 43%

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
