A round ball is kicked into the air at an angle of 39 degrees above the horizontal. The initial velocity of the ball is 32 m/s.
A. How long is the ball in the air?
B. What is the horizontal distance traveled by the ball?
C. What is the maximum height reached by the ball?

In this experiment, you will use a track, a toy car, and some washers to explore newton’s first two laws of motion. you will make observations and collect data regarding the motion of these objects. in the space below, write a general scientific question that you will answer by doing this experiment.

Calculate the kinetic energy of earth due to its spinning about its axis. krot = j compare your answer with the kinetic energy of the orbital motion of earth's center of mass about the sun. assume earth to be a homogeneous sphere of mass 6.00 1024 kg and radius 6.40 106 m. the radius of earth's orbit is 1.50 1011 m.

How would doubling the made of an object change the objects potential energy
