8. A person standing on a 25-m high ledge atop a cliff drops a rock. At the same time, another person at the base of the cliff throws another rock straight upward at a speed of 15 m/s. Assume that air resistance is negligible and g = 9.8 m/s². How high from the base of the cliff will the two rocks meet?

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)
3. You are watching a fancy celebration which includes fireworks. These are shot from a movable platform standing at a height of 30 m above ground. They are shot straight upwards, and reach a maximum altitude of 150 m from the platform. Accidentally, one of the fireworks does not explode and falls back to the ground, nearly missing the platform. You can assume the trajectory to be perfectly vertical. You may ignore air resistance. Take the magnitude of g to be 9.8 m/s². a. Draw a sketch of the situation, labeling the height of the platform, the initial velocity of the maximum elevation of the firework, the (unknown) initial velocity of the firework, and the (unknown) velocity of the firework just before it hits the ground. b. What is the velocity of the firework at the peak of its trajectory? c. How long does it take the firework to reach the peak of its trajectory? d. What is the initial velocity of the firework? e. What is the total time that the firework spends in the air? f. What…
