A car has a mass of 1700 kg and is moving at a speed of 25 m/s. Find its momentum.

Two particles (m1 = 0.20 kg, m2 = 0.30 kg) are positioned at the ends of a2.0-m long rod of negligible mass. What is the moment of inertia ofthis rigid body about an axis perpendicular to the rod and throughthe center of mass? A) 0.48 kg * m2B) 0.

A car moving at 10.0 m/s crashes into a barrier and stops in 0.050 s. There is a 20.0-kg child in the car. Assume that the child's velocity is changed by the same amount as that of the car, and in the same time period.

Cold water (cp = 4180 J/kg·K) leading to a shower enters a thinwalled double-pipe counterflow heat exchanger at 15°C at a rate of 1.25 kg/s and is heated to 60°C by hot water (cp = 4190 J/kg·K) that enters at 100°C at a rate of 4 kg/s.
