QUESTION 1 A ball of mass 5.0kg is lifted off the floor a distance of 1.7m. 1. What is the change in the gravitational potential energy of the ball? 2. Now you release the ball from rest, and it falls to the floor. What is the kinetic energy of the ball just before it hits the floor? 3. What is the velocity of ball just before it hits the floor? QUESTION 2 Suppose that the ball in the last question...

A ball with mass m is thrown vertically upwards with initial speed vo- Assuming lnear air drag write down and solve the equation of motion for the ball, i.e. find the time dependence of its position. Find the coordinate of the highest point of the trajectory as well the time needed to reach it.

1. 2. A spring-loaded toy gun is used to shoot a ball of mass M straight up in the air. The ball is not attached to the spring. The ball is pushed down onto the spring so that the spring is compressed a distance S below its unstretched point. After release, the ball reaches a maximum height 35, measured from the unstretched position of the spring (see diagram below). Maximum Height Spring unstretched Spring compressed Mass released from west will...

1. A marble is fired into the air at 12m/s at an angle of 35° from vertical. It lands 1.25 m lower than its launch height. What is the maximum height that it reaches above its landing location? When does it reach this height? When does it land? What is its velocity (speed and direction) when it lands? Max height Time at max height = Time of landing- Velocity at landing - 2. The Space Shuttle used to fly...

Group Activity: Ball rolling down ramp and off cliff As shown in the figure below, a hollow ball with a mass m 5.00 kg and radius r -30.0cm starts from rest and rolls a distance of 1.2 m down a 30° ramp, before reaching a flat section at the bottom of the ramp. The ball then rolls along the flat section for 1.0 m before rolling off a 2.5 m-high cliff. The ball lands a distance d from the bottom...

the ball and the pendulum cup have the same velocity after the collision. As is the case with any collision, total momentum is conserved (unchanged). Using conservation of momentum, write down an equation for Vealefore in terms of the velocity of the hall together with the pendmcu ( d the mass of the al and that of the cup (meup). ball before= Using conservation of energy between...

Allison throws a tennis ball at time t = 0 from a height h above the ground equal to her own height. We assume that the positive horizontal direction is the positive x-direction, and the positive vertical direction is the positive y-direction. The ball has a positive initial horizontal velocity vx, and no initial vertical velocity. At times t1 and t2, the ball bounces on the ground for the first, and second times respectively after being thrown. We assume that...
