The force of friction is 6.00x10^2 N. Write an equation to isolate and solve for P.SCSU physics and astronomy student club has a recently established tradition of pumpkin drop, from the top of Wick Science Building to the "moat" below street level. Although the "experimental data" have not been made public, there have been rumors of the drop took 2.20 seconds, i.e. falling from rest with negligible air drag. Based on the rumor, how tall is the building from the "moat" to the roof? Ignore air drag or any rotation of pumpkins. Hint: You may assume final position to be zero.

- A space shuttle lands on a distant planet where the gravitational acceleration is 2.0 ( We do not know thelocal units of length and time , but they are consistent throughout the problem). The shuttle coasts along aleve, frictionless plane with a speed of 6.0. It then coasts up a frictionless ramp of height 5.0 and angle 0f 30°.After a brief ballistic flight, it lands a distance S from the ramp. Solve for S in local units of length. Assume theshuttle is small compared to the local length unit and that all atmospheric effects are negligible. Use x and y components.A winding drum raises a cage through a height of 120 m. The cage has, at first, an acceleration of 1.5 m/s2 until the velocity of 9 m/s is reached, after which the velocity is constant until the cage nears the top, when the final retardation is 6 m/s2. Find the time taken for the cage to reach the top.A small boat is being pushed up a ramp into the back of a flatbed truck. The boat is sitting at the top of the ramp, which is located 1.4 m above the ground. The boaters think the boat is safe there, and begin to walkaway. However, they have neglected the thin layer of ice that has formed on the ramp, which is angled at 30◦ up from the ground. Neglecting the friction between the boat and the ramp, how long do the boaters havebefore the boat reaches the bottom of the ramp?
