4. At the construction site of a tall building, a worker is in an elevator descending at a constant downwards velocity of 5 m/s. When the elevator is 40 meters above ground level, her friend, standing at ground level, tosses a wrench straight upward with an initial speed of 25 m/s. Take the time when the wrench is tossed as t = 0. For this problem, use g = 10 m/s². a. Draw a labeled picture with symbols and all relevant values. Quantities that are different should be given different symbols, for example y, and Yw. b. Graph the velocities versus time of the elevator and the wrench on the same graph. Label axes of the graph (with units). C. At what time does the wrench and the elevator have the same velocity? 20 10 -10 -20 3 4 time (s) d. Which object (the wrench or elevator) is higher when their velocities are the same? By how much is one object higher than the other at this time? (s/u) ka

A rocket is launched from a height of 3 m with an initial velocity of 15 m/s. At what time will the rocket be 13 m from the ground?

Please explain and give the final answer for this problem. I keep getting wrong answers after calculations.

Julie, mass 36kg, has invented a new ride called the Human Launcher. It is basically a platform that springs people straight up into the air. She is testing it, standing on a bathroom scale on the platform. As the platform springs 10.0m upward from rest, Julie notices the scale reads 600.0N. Once it reaches ground level, the platform suddenly stops, but Julie doesn't, and is launched up into the air. What is the maximum height above the ground that Julie will reach? (the ride was deemed unsafe and cancelled) *= nut 10.0m ground

I need help with d, e, f, and g as well.

A frictionless rolling cart has an initial velocity of 10.0 m/s as it climbs up anincline of 24 degrees .a. What is the cart’s height above the ground when it monetarily comes to astop on the ramp?b. At that instant, how far has it travelled along the ramp?

A basketball is thrown at 45° to the horizontal. The hoop is located 3.6 m away horizontally at a height of 1.2 m above the point of release. What is the required initial speed? m/s

6. A crazy, young boy on a sled is able to get up to an incredible speed of 22.5 m/s (yes, he is wearing a helmet!) along a frictionless horizontal surface while he approaches an icy hill with a vertical height of 11 m, as shown. He makes it to the top, and then flies off horizontally from the ledge of the hill. How far from the base of the hill does the boy land? 225 mis Figure 1
