A 25 kg arrow strikes a target with a momentum of 3 kg m/s. What is its velocity?

An incident ray through the focal point of a spherical mirror will: reflect through the center of curvature. reflect back through the focal point. reflect parallel to the principle axis. reflect the same direction as the incident ray.

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.

Aproper cool-down routine does which of the following? a). motivates you for your next workout b). the body adjust back to a resting state c). leaves you feeling worn-out d). strengthens muscles
