How the total energy will change when the mass of the object becomes four times.

Question

Consider the free-fall motion of a bouncing ball. Assume that there is very little air resistance. Let the floor be the zero point. For this activity we will predict how the energy will change as the ball bounces from just leaving the floor, through one complete bounce until It just hits the floor a second time. Height and velocity of a single bounce Figre2 Heghr and Question 1: Make a sketch of both position vs. time and velocity vs time for the ball from just after it hits the floor for the first time, through one complete bounce until it hits the floor a second time. Let the floor be the zero point. This will look similar to the pop-out image above in Figure 2. On your sketch, label the positions (a-e): a. the ball has just left the floor and is on its way up b. the ball is about halfway up C. the ball is at the highest point of the bounce d. the ball is about halfway back down e. the ball is almost back down to the floor

The two equations below express conservation of energy and conservation of mass for water flowing from a circular hole of radius 3 centimeters at the bottom of a cylindrical tank of radius 10 centimeters. In these equations, Am is the mass that leaves the tank in time A t, v is the velocity of the water fiowing through the hole, and h is the height of the water in the tank at time t. g is the accelertion of gravity, which you should approximate as 1000 cm/s?. The first equation says that the gain in kinetic energy of the water leaving the tank equals the loss in potential energy of the water in the tank. am v? - Am g h The second equation says that the rate at which water leaves the tank equals the rate of decrease in the volume of water in the tank (which is conservation of mass because water has constant density). z 102 dh -x 32 v Derive a differential equation for the height of water in the tank. dh dt If the initial height of the water is 30 centimeters, find a formula or the…

Answer the following problem with the complete step-by-step process (showing the given, required, process/solution, and graph if possible). 1. A 15.0-g bullet is accelerated from rest to a speed of 780 m/s in a rifle barrel of length 72.0 cm. (a) Find the kinetic energy of the bullet as it leaves the barrel. (b) Use the work–kinetic energy theorem to find the net work that is done on the bullet.
