Two particles, A and B, are moving in a straight line. Take this to be the x-axis. At t = 0, particle A is trailing particle B, initially at some distance x behind B. Particle B
is accelerating at a constant 2.00 m/s2 and particle A is constantly accelerating at 3.00
m/s2
. Particle A was able to overtake B after B has moved 50.0 m.
(a) How long does it take for particle A to overtake B?
(b) Initially, how far was A behind B?
(c) How fast are the two particles moving as soon as they’re at the same position?

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
