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 maximum height?

A block of mass 0.250 kg is placed on top of a light, vertical spring of force constant 5 000 N/m and pushed downward so that the spring is compressed by 0.100 m. After the block is released from rest, it travels upward and then leaves the spring. To what maximum height above the point of release does it rise?
A block of mass 0.240 kg is placed on top of a light
A block of mass 0.240 kg is placed on top of a light, vertical spring of force constant 5 200 N/m and pushed downward so that the spring is compressed by 0.094 m. After the block is released from rest, it travels upward and then leaves the spring. To what maximum height above the point of release does it rise? (Round your answer to two decimal places.)

A Block of Mass 0.5 Kg is placed on top of a light, vertical spring of...
A Block of Mass 0.5 Kg is placed on top of a light, vertical spring of spring constant 50 N/m, causing the spring to compress some amount. The block is then pushed downwards by a persons hand so that the spring is compressed an additional 15 cm. The block is then released from rest, so that it travels upward and then leave the spring. A. What is the kinetic energy of the block as it leave the spring? B. What...

1 Warm-Up Questions 1 A block of mass m = 3 kg is dropped from the top of a half-pipe (half-circle) of radius R = 2 m starting from rest. The surface of the incline does have friction. If the block comes to rest at half of its initial height, how much work was done by friction? Work: 2 Initially, a ball of mass 0.4 kg is compressed by a spring, with spring constant k = 980 N/m, by a...

A wooden block with mass 1.95 kg is placed against a compressed spring at the bottom of a slope inclined at an angle of 35.0degree (point A). When the spring is released, it projects the block up the incline. At point B, a distance of 4.00 m up the incline from A, the block is moving up the incline at a speed of 6.15 m/s and is no longer in contact with the spring. The coefficient of kinetic between the...
