2. (a) A ball is fired from a cannon straight up at a velocity of 30ms^ - 1. The ball leaves the cannon at a height of 5 m that is vertically above the ground. Find the time taken until the ball hits the ground. Find the velocity of the ball when it hits the ground. If the ball had been projected at 10 ms^ - 1 instead of 30 ms^ - 1, what would its final velocity when it...

A cat's crinkle ball toy of mass 35 g is thrown straight up with an initial speed of 7 m/s. Assume in this problem that air drag is negligible. (a) What is the kinetic energy of the ball (in J) as it leaves the hand? (b) How much work is done (in J) by the gravitational force during the ball's rise to its peak? (c) What is the change in the gravitational potential energy of the ball (in J) during...

a. Question 4 [15 points) A cannon of mass 40 kg resting in the chamber of a projectile launcher is projected straight upwards, giving the cannon an initial velocity of 30.0 m/s. Assuming the cannon travels in a region free from non-conservative forces: How much work is done by the projectile launcher on the cannon? [2 points) b. How much work must be done to stop the cannon when it is at a 2 points) height 60% of its total...

A spring-loaded launcher is used to shoot a ball of mass 1.50 kg straight up in the air, as shown in (Figure 1). The spring has spring constant k 667 N/m. If the spring is compressed a distance of 25.0 centimeters from its equilibrium position y = 0 and then released, the ball reaches a maximum height hmax (measured from the equilibrium position of the spring). There is no air resistance, and the ball never touches the inside of the...

A ball of mass 0.083 kg is shot straight up in the air using a compressed spring. The spring has a spring constant of 328 N/m and is compressed by 0.05 m initially. The ball reaches a height of 0.252 m above the initial position. How much energy has dissipated due to frictional effects such as air drag ? (in J)

A ball is thrown straight up such that it leaves your hand with 200 Joules of kinetic energy. Suppose we choose the ball + Earth as our system and we use the height of the ball when it leaves your hand as h = 0. Answer the questions below ignoring air resistance. Initial gravitational potential energy when the ball leaves your hand = Kinetic energy when the ball is half way to its maximum height = j. Gravitational potential energy...

(10 marks) A small catapult is used to launch 1.5 kg water balloons straight up into the air. A clever student is able to measure the speed of the water balloon while it is rising up into the air. She finds that the water balloon is 8.0 m above the catapult it is moving at a speed of 20.0 m/s. (For the purposes of this question, assume that the catapult is positioned in a small hole so that the height...
