Evan is a championship runner of the school's track team. During one of his trials, his speed was measured at 8 m/s. Find Evan's
kinetic energy during that trial if his mass is 58.6 kg.
A-1875j
B-2990j
C-855 J
D-1240J

An experiment is designed to test the relationship between the initial height of a basketball before it is dropped to the height of its rebound bounce. the height of the rebound bounce is measured using a scale positioned behind the ball. in the above experiment, which condition would not be controlled? a). the starting height of the ballb). the surface the ball bounces on c). the type of ball d). the method to measure the rebound height of the ball

Calculate the heat capacity per object when the total energy is 4 quanta. (think of this in terms of increasing from 3.5 quanta of energy in the system to 4.5 quanta of energy in the system, if that were possible.) c4 = __ j/k/object

What are the three ways that an object can accelerate
