newton's’ second law practice

1. a bowling ball rolls down the lane at 2.3 m/s2 . if the ball weighed 14 kg, what is the force of the ball?

2. a car races at 6.4 m/s2 and has a force of 1473n. how much does it weigh?

3. a turtle has a force of 94n. if he weighs 45kg, how fast is he accelerating?

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.
