A20-ton truck collides with a 1500-lb car and causes a lot of damage to the car. since a lot of damage is done on the car : select one:
a. the force on the truck is smaller than the force on the car.
b. the truck did not slow down during the collision.
c. the force on the truck is greater then the force on the car.
d. the force on the truck is equal to the force on the car.

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.
