A projectile launcher sits atop a tall building. The launcher fires the projectile with an initial velocity of 7.0 m/s at an angle of 28° above horizontal. Using the point of launch as a reference point what is the magnitude of the position vector for the projectile 1.5 seconds after being launched? 9 to 10 meters greater than 14 meters 12 to 13 meters less than 9 meters 10 to 11 meters 11 to 12 meters 8 to 9 meters...

Your answer Question cover CLO2: 10 Marks Q 1)-- A 0.2 kg billiard ball moving with a 10 points speed of 10 m/s along the + x-axis, approaches an identical ball at rest, as shown in below. The collision between the balls is elastic. After the collision the incident ball moves with a speed of 6.43 m/s at an angle of 50degree below the + x-axis. What is the angle at which the target ball moves after the collision is?...

A 500 kg cannon fires a 2.5 kg projectile with a velocity of 400 m/s parallel to the ground. The projectile hits a target which is 120 m away from the cannon. What is the recoil speed of the cannon?

A projectile launcher as shown in the Figure is used to launch 0.5 kg ball into the air. The launcher is connected to a 1kg mass and starts from rest with the spring compressed to a length of 15 cm. The un-stretched length of the spring is 75 cm. When the launcher is released from rest, the 1kg mass will impact the ball and the ball wil project in the air. Determine a suitable spring constant and angle 8 for...

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...

Part B: Launching a Projectile at an Angle (1) Erase the trajectory from part A (yellow eraser button). (2) Ensure that the initial height (h = 10 m) and initial speed (1 = 15 m s 1) remain equal to the quantities given in part A. (3) Position the projectile launcher so that it launches at an angle of 20°. (4) Fire the launcher (using the red fire button) and record the x-displacement by positioning the center of the target...

A cannon fires a ball horizontally with a velocity of 240 m/s. If the cannon is in a 44 meter tall tower and the ground below is flat, then (a) How long does the ball take to hit the ground after being fired? (b) At what horizontal distance from the cannon does the ball hit the ground? and (c) What are the horizontal and vertical components of the ball's velocity just before it hits the ground?

1) a)You are asked to find the initial velocity of a steel ball from a spring loaded launcher. You place the launcher on the edge of a table 1.0 meter above the floor and launch the projectile several times horizontally. If you find that the average distance the ball travels is 1.3 meters, what is the initial velocity of the ball? To solve a problem like this, use equations for the y-motion to find the time and then the x-motion...

Part A A small spring-loaded launcher is designed to fire steel ball bearings with masses of 0.28 kg. When setting the launcher, you compress the spring a distance of 13 cm. You then fire the launcher straight up and find that the projectiles reach a maximum height of 1 m above the point that they leave the launcher. You load another ball bearing, compress the spring a distance of 19 cm, and place it horizontally at the edge of a...

A 0.2 Kg ball is dropped with no initial velocity from a height of 6 m. It drops vertically with no air drag, it hits the flat, concrete ground and re-bounces upward in a vertical direction reaching a maximum height of 4 m. (i) Calculate the speed of the ball when it hit the ground. (ii) Calculate the speed of the ball when it began moving upward. (iii) Calculate the magnitude of the impulse provided by the ground to the...
