You want to nail a 1.3-kg board onto the wall of a barn. To position the board before nailing, you push it against the wall with a horizontal force F to keep it from sliding to the ground.
a.) f the coefficient of static friction between the board and the wall is 0.80, what is the least force you can apply and still hold the board in place?
b.) What happens to the force of static friction if you push against the wall with a force greater than that found in part A?
In a lightning bolt, a large amount of charge flows during a time of 2.1 x 10-3 s. How much charged has flowed during the lightning bolt?
Atomic nuclei have a typical density of about 10^(17) kg/m^3. The density of liquid mercury is roughly 10^(4) kg/m^3. Approximately what fraction of the volume of liquid mercury is empty space between mercury nuclei?
A pendulum of length 9.00 m is held out to point A. At the vertical position, an overhang effectively cuts the length of the pendulum by an amount equal to 3m. (That is, 3.0 m is no longer free to swing.) How long does this pendulum take for one o..

Suppose a car's brakes can produce an acceleration of -7 m/s2. what is the minimum distance necessary to stop the car
A car of mass M = 1200 kg traveling at 45.0 km/hour enters a banked turn covered with ice. The road is banked at an angle theta, and there is no friction between the road and the car's tires.
A boy in a wagon is moving at 3.1 m/s east when another boy begins pulling on the wagon in the direction opposite to its motion at 1.25 m/s^2. (a) How long does it take to give the wagon a velocity of 7.4 m/s west? (b) How far from the starting po..
