a cannonball with a mass of 6.95 kg is placed in a vertical, spring-loaded cannon bearing a spring with a spring constant of 5.6 newtons/meter. The spring is compressed by a distance of 4.54 meters and released. Please use g=9.80 m/s2. The max height reached by the cannonball in meters is?

A Huntress fires a bullet into a 3-kg wooden block resting on a smooth surface, and attached to a spring of spring constant 715. N/m. The bullet, whose mass is 7 g, remains embedded in the wooden block. She measures the maxumum distance that the block compresses the spring to be 4.50 cm. What is the speed of the bullet (in m/s)? (So the block is at equalibrium on a horizontal surface with a spriing attatched to the one side, which is then attatched to the wall. What equation am I able to use to find the speed of the bullet?)

A 2.0 kg block is placed against a spring on a frictionless 30 degrees incline (from the horizontal). The spring, whose spring constant is 1960 N/m, is compressed 20 cm and then released. How far along the incline does it send the block? (Ans.= 4m)

An 8.0-g bullet is suddenly shot into a 4.0-kg block that is at rest on a frictionless horizontal surface, as shown in the figure. The bullet remains lodged in the block. The block then runs into a spring bumper and compresses it by 3.7 cm. The force constant (spring constant) of the spring is 2500 N/m. What was the initial speed  v of the bullet?

A factory worker drops a 10 kg steel block from rest (m=10). The block then falls 30 cm onto a vertical spring standing on the floor. The spring constant of the spring is 400 N/m (k=400). The block makes contact with the spring, it then continues to move downward, compressing the spring until it comes to rest. (The spring then decompresses, firing the block upward.) Determine the distance that the spring was compressed by the block.

A spring-loaded toy gun is used to shoot a ball of mass m = 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 gun. Assume that all movement occurs in a straight line up and down along the y axis.

A 1.30 kg block slides on a frictionless horizontal surface until it encounters a spring with a force constant of 520 N/m. The block comes to rest after compressing the spring by the distance of 2.50 cm.What was the initial speed of the block ? O 0.25 m/s 5.0 m/s O 31.6 m/s O 0.50 m/s

A block of mass, 1.5 kg is attached and secured to an end of a spring with a spring constant of 10,000 N/cm. The other end of the spring is secured to the wall. The block is pushed against the spring, which compresses the spring to a position of x = -0.04 cm. When uncompressed, the end of the spring that is attached to the block is at a position of x = 0.00 cm. The block/spring system is then released from rest, and the block travels along a rough horizontal track for the length of the spring. At 0.00 cm the surface changes. Can you help me calculate the block's velocity once it leaves the spring? Thank you.
