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.

4. A block of mass 0.25 kg is placed on a vertical spring of constant k- 5000 N/m, and is pushed downward compressing the spring a distance of 0.1 m. As the block is released, it leaves the spring and continues to travel upward. To what maximum height above the point of release does the block rise?

Ball A (m 0.5 kg, I 0.7 MR2) is held at rest against a spring, compressed by a distance x-40 cm. The ball is released and move along a frictionless surface (Ho 4 m) until it collides with ball B (m- 0.25 kg, I- 0.5 MR2) which is at rest. After the collision, the two balls roll down a track (which has friction!) and leaves the track at a height, H,- 1m. Ball B goes to a height of HB-5m...
A vertical spring (ignore its mass), whose spring constant is 875 N/m , is attached to a table and is compressed down by 0.160 m. What upward speed can it give to a 0.320-kg ball when released?
A vertical spring (ignore its mass), whose spring constant is 875 N/m , is attached to a table and is compressed down by 0.160 m. A) What upward speed can it give to a 0.320-kg ball when released? B) How high above its original position (spring compressed) will the ball fly?

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...

3. Work and Energy A block of mass 0.50 kg is placed on top of a spring with negligible mass and force constant 5,000 N/m. Initially, the spring is compressed by 0.100 m. After the block is released from rest, it travels vertically upward and leaves the spring. a) What is the speed of the block when it leaves the spring? b) What maximum height does the block reach? c) What is the velocity of the block half-way to the...

The spring of a spring gun has force constant k = 450 N/m and negligible mass. The spring is compressed 6.40 cm and a ball with mass 0.0270 kg is placed in the horizontal barrel against the compressed spring. The spring is then released, and the ball is propelled out the barrel of the gun. The barrel is 6.40 cm long, so the ball leaves the barrel at the same point that it loses contact with the spring. The gun...

A 1.16-kg box rests atop a massless vertical spring with k = 4100 N/m that has been compressed by 14.2 cm from its equilibrium position. The box is released and leaves the spring when it reaches its equilibrium position. What is the maximum height the box reaches above its original position? cm
