Which would take more force to stop in 10 seconds: an 8.0-kilogram ball rolling in a straight line at a speed
of 0.2 m/sec or a 4.0-kilogram ball rolling along the same path at a speed of 1.0 m/sec?
8.
The momentum of a car traveling in a straight line at 20 m/sec is 24,500 kg-m/sec. What is the car's mass?
9.
A 0.14-kilogram baseball is thrown in a straight line at a velocity of 30 m/sec. What is the momentum of the
baseball?
10. Another pitcher throws the same baseball in a straight line. Its momentum is 2.1 kg m/sec. What is the
velocity of the ball?

Consider a u-tube whose arms are open to the atmosphere. now equal volumes of water and light oil (ρ = 49.3 lbm/ft3) are poured from different arms. a person blows from the oil side of the u-tube until the contact surface of the two fluids moves to the bottom of the u-tube, and therefore, the liquid levels in the two arms are the same. if the fluid height in each arm is 30 in, determine the gage pressure exerted by the person on the oil by blowing.
