Q. A person jumps up and down on a trampoline, while staying in contact with it. The motion is simple harmonic motion and it takes 1.90s to complete one cycle. The height of each bounce above the equilibrium position is 0.45cm. Determine (a) the amplitude and (b)the angular frequency of the motion. (c)What is the highest speed attained by the person?
the speed at which the ball left the quarterback's hand.
compute the linear speed due to the Earth's rotation for a person at a point on its surface located at 40o N latitude (this would be near the Ohio river valley, for instance). The radius of the Earth is 6.40 ξ 106 m. (For comparison, the speed of ..

Two objects are charged and their centers are separated by 31.6 cm. Object A is charged to 61 nC and object B is charged to 54 nC. What is the magnitude of the electrostatic force between them.
A cat runs along a straight line (the x-axis) from point A to point B to point C. The distance between points A and C is 5.00 m, distance between points B and C is 10.0 m, and the positive direction of x axis points to the right. The time to run f..
