: Calculate (a) the impulse experienced when a 70 kg person lands on firm ground after jumping from a height of 3.0 m and (b) Estimate the average force exerted on the person’s feet by the ground if the landing is stiffed leg (c) with bend legs. (With stiff legs, assume the body moves 1.0 cm during impact and when the legs are bent about 50 cm)

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
