4. A spring gun with a spring constant, k = 50 N m , is loaded with a 60g ball and placed on a 1.5m high platform. (a) If the spring in the gun is compressed by 4.0cm, how fast would the ball be moving once it is fired and is no longer contacting the spring? answer (b) If the spring in the gun is compressed by 4.0cm, how far from the end of the gun will the ball travel...

A toy gun uses a spring with a force constant of 350 N/m to propel a 14.0 g steel ball. The spring is compressed 8.80 cm and friction is negligible. (a) How much force (in N) is needed to compress the spring? (Assume the gun is aimed in the positive direction. Indicate the direction with the sign of your answer.) (b) To what maximum height (in m) can the ball be shot? (c) At what angles above the horizontal (in...

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?

6. You throw a ball out of a window at 4 m/s at a downward 30° angle. As a result, it takes 1.5 seconds for the ball to hit the ground. 30 A. How far does this ball travel horizontally before hitting the ground? (5.2 m) B. How high is this window from the ground? C. What is the velocity of this ball just before it hits the ground? Report your answer using components, or calculate the magnitude and direction.

A massless spring of a spring gun has a force constant k=800 N/m. A ball of mass 0.5 kg is resting on top of the spring. The ball compresses the spring by d as shown in the right figure. When the gun is fired vertically, the ball reached a maximum height of 5 m from the top of the spring as it returns to its natural length. Calculate how much the spring was initially compressed (d). (a) 12 cm; (b)...

A marble is rolled horizontally off a 0.855 m tall table with a speed of 62.3 cm/s. How far will the ball travel horizontally (in cm) before hitting the ground?

A small spring-loaded launcher is designed to fire steel ball bearings with masses of 0.26 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 1.2 m above the point that they leave the launcher. You load another ball bearing, compress the spring a distance of 16 cm , and place it horizontally at the edge of...

A small spring-loaded launcher is designed to fire steel ball bearings with masses of 0.3 kg . When setting the launcher, you compress the spring a distance of 14 cm . You then fire the launcher straight up and find that the projectiles reach a maximum height of 0.9 m above the point that they leave the launcher. You load another ball bearing, compress the spring a distance of 20 cm , and place it horizontally at the edge of...
A dart gun is fired while being held horizontally at a height of 1.00 m above ground level and while it is at rest relative to the ground
A dart gun is fired while being held horizontally at a height of 1.00 m above ground level and while it is at rest relative to the ground. The dart from the gun travels a horizontal distance of 5.00 m. A college student holds the same gun in a horizontal position while sliding down a 45.0° incline at a constant speed of 2.00 m/s. How far will the dart travel if the student fires the gun when it is 1.00...
