A kicker's foot is in contact with the football for only 0.008 seconds, and in that time the kicker applies one ton of force (~9800 N). What is the impulse of the force in units of N*s

Write the equation for momentum, first using symbols for the variables, then using words for the variables.

The space between two 15-in.-long concentric cylinders is filled with glycerin (viscosity = 8.5 × 10-3 lb·s/ft2). the inner cylinder has a radius of 1 in. and the gap width between cylinders is 0.1 in. determine (a) the torque and (b) the power required to rotate the inner cylinder at 180 rev/min. the outer cylinder is fixed. assume the velocity distribution in the gap to be linear.
