Aman pushes a 60.8 kg crate across a rough surface with an applied force of 125 n and at a constant speed.

what is the magnitude of the force normal acting on the box?

Amira pulls a 3 pound wagon 4 feet. how much work has she done?

What is the relationship between the direction of motion of the balloon and the wind currents

Amass weighing 24 pounds, attached to the end of a spring, stretches it 4 inches. initially, the mass is released from rest from a point 8 inches below the equilibrium position. find the equation of motion. (use g = 32 ft/s2 for the acceleration due to gravity.)
