Atennis ball of mass m = 0.060 kg is traveling with a speed of 28 m/s and θ = 35 degrees. it strikes a wall and bounces off with a speed of 28 m/s. what is the magnitude of the force, in newtons, exerted on the ball if the collision time is 0.1 s? what direction was the force exerted by the wall?

Curious carl calculated the density of a cube to be 4.50 g/cm3. what is the density of the cube in g/l?

Light traveling in water, nwater = 1.33, strikes a plastic block at an angle of incidence of 51.4°; part of the beam is reflected and part is refracted. if the index of refraction of the plastic is 2.0, what is the angle made by the reflected and refracted beams?

An ascending elevator, hanging from a cable, is coming to a stop. part a part complete identify all forces acting on the elevator from the list below. select all that apply. select all that apply. kinetic friction normal force tension weight static friction submitprevious answers correct part b draw a free-body diagram of the object. draw the vectors starting at the black dot. the location and orientation of the vectors will be graded. the exact length of your vectors will not be graded but the relative length of one to the other will be graded.
