3. To the finite! A block with mass ? = 1.20 [kg] at rest is pressed against a spring with spring constant ? = 255 [N/m], compressing it by 18.0 [cm]. The mass is then let go, and goes up a ramp inclined at an angle ? = 35.0 ◦ above the horizontal. A. What is the speed of the block immediately before it goes up the incline?B. How far along the incline’s length does the block travel until it comes to a rest?
You are playing a game and you push a cart to give it in. speed. The cart starts at the bottom (zero) of a ramp and after reaching the top of the ramp, the cart travels across a horizontal track w/ friction. The mass of the cart is 44 x 10^-3 kg. The ramp is 56 cm high. The length is 70 cm. What can you infer of the intial speed in (m/s)

A 50 g ice cube can slide without friction up and down a 30º slope. The ice cube is pressed against a spring at the bottom of the slope, compressing the spring 13.0 cm. The spring constant is 25 N/m. When the ice cube is released, what distance (in cm) will it travel up the slope above the release point before reversing direction? Use g = 10 N/kg. In your calculations, make sure you convert to consistent units (kg and meters).
A 2.0-kg mass is attached to a vertical spring. The mass is held in place with the spring relaxed, and then released from rest. As the mass falls, it stretches the spring.
