In an 84 s interval. 959 hailstones strike a glass window of area 1.202 mº at an angle 44°

to the window surface. Each hailstone has a

mass of 5 g and speed of 11.4 m/s.

If the collisions are elastic, find the average

force on the window.

Answer in units of N.

Answer in units of N

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.

answer is slate
