What is the speed of the truck
A baseball pitcher can throw a ball with a speed of 70 {rm m/s}. He is in the back of a pickup truck that is driving away from you. He throws the ball in your direction, and it floats toward you at a lazy 20 {rm m/s}. What is the speed of the truck?

A block with a mass of 10g is pulled at a constant speed across a horizontal tabletop with a spring scale. the scale reads 65.3N. calculate the coefficient of kinetic friction.
A curve of radius 60 m is banked for a design speed of 100 km/h. If the coefficient of static friction is 0.30 (wet pavement), at what range of speeds can a car safely make the curve?
Two charged pith balls are suspended on very light 10.5 cm strings. Each has a mass 11.0g. In equilibrium, the total angle between the strings is 35 degrees. Draw a free body diagram for one of the pith balls and clearly label all forces with magn

Three charges are arranged in a square (along with point P) with sides equal to 12.5cm as in figure below. Calculate the electric field (magnitude and direction) at point P due to the three charges. Next, calculate the force (magnitude and directi
A grocery cart with mass of 18 kg is pushed at a constant speed along an aisle by a force F = 12 N. the applied force acts at a 20 degree angle to the horizontal. find the work done by each of the forces on the cart if the aisle is 15 m long.
The coefficient of kinetic friction between each brake pad and the rim is μk = 0.85. What is the magnitude of the normal force that each brake pad applies to the rim?
