A boy pulls a 48 kg crate with a rope horizontally across the floor. The coefficient of kinetic triction for the crate and the deck is 0.300. The boy exerts a force of 185 N. Draw a free body diagram of the forces acting on the crate. Does the crate accelerate, and if it does at what rate? How fast is it going after 1.2 s, it it started at rest?

What is the maximum acceleration of the wing tips, in units of g?

Apropagating wave in space with electric and magnetic components. these components oscillate at right angles to each other. it may travel in a vacuum. determine the term.

Suppose a force of 60 n is required to stretch and hold a spring 0.1 m from its equilibrium position. a. assuming the spring obeys hooke's law, find the spring constant k. b. how much work is required to compress the spring 0.5 m from its equilibrium position? c. how much work is required to stretch the spring 0.6 m from its equilibrium position? d. how much additional work is required to stretch the spring 0.1 m if it has already been stretched 0.1 m from its equilibrium? a. kequals 600
