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

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
