A worker pushes a box across the floor to the right at a constant speed with a force of 25N. What can you conclude about the box?

If the speed of a particle triples ,by what factor does its kinetic energy increase?

What object a collides with object b and bounces back its final momentum is?

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.
