The four tires on the author's car are inflated to an absolute pressure of 2.8 x 105 Pa. If the car has a mass of 1,650 kg, what is the contact area between each tire and the ground?
An 87.6 g lead ball is dropped from rest from a height of 5.60 m. The collision between the ball and the ground is totally inelastic. Assuming all the ball's kinetic energy goes into heating the ball, find its change in temperature.
In a typical lightning flash, the potential difference between the cloud and the ground is 10^9 V and the charge transferred is 30 C. Calculate the final speed of the car
A rectangular channel n=0.012, 3.05m wide laid on a slope of 0.0049 carries 13.6 m^3/s. The channel is to be contracted to produce critical flow. What width of contracted section will accomplish this, neglecting any loss in the gradual reduction in w..
A billiard ball strikes and rebounds from the cushion of a pool table perpendicularly. What is the average net force (magnitude and direction) exerted on the ball by the cushion
A small .500 kg object moves on a frictionless horizontal table in a circular path of radius 1 m. The angular speed is 6.28 rad/s. The object is attached to a string of negligible mass that passes through a small hole in the table at the center of..

A skateboarder shoots off a ramp with a velocity of 7.4 m/s,directed at an angle of 55° above the horizontal. The end ofthe ramp is 1.4 m above the ground. Let the x axis beparallel to the ground, the +y direction be verticallyupward, and take as ..
You place 108 moles of hydrogen gas in a balloon of volume 2.3 m3, and find the pressure to be 1.6 times atmospheric pressure. What is the typical speed of a hydrogen molecule?
A heat pump has a coefficient of performance equal to 4.35 and requires a power of 1.77 kW to operate. How much energy does the heat pump add to a home in one hour
A person, with his ear to the ground, sees a huge stone strike the concrete pavement. A moment later two sounds are heard from the impact: one travels in the air and the other in the concrete, and they are 6.60s apart. How far away did the impact ..
