**Question 10**A 1 kg skate rat drops from the top of a 3 m high half-pipe ramp. Ignoring friction, how much Kinetic Energy would s/he have at the lowest point of the ramp?- ○ 100 Joules- ○ 300 Joules- ○ 3 Joules- ○ 30 Joules---**Question 11**Ignoring friction, what would be the velocity of the skate rat in the question above at the lowest point of the ramp?- ○ √60 m/s- ○ √6000 m/s- ○ √3 m/s- ○ √30 m/s---**Question 12**In the real world, the skate rat above would lose some speed/energy due to friction. If it loses 10 Joules of energy while moving from one side of the ramp (where s/he dropped in) to the other side of the half-pipe, how far (in meters) would the skate rat make it up the other side?- [Text box for input]

Given that the mass of the skate rat is m = 1Kg its is drop from 3 m height so its has potential energy Potential energy is given by P = m*g*h where g is a gravity (=10m/s2 ) P = 1*10*3 P = 30J when rats reach at the lowest point its all potential energy convert into kinetic energy so the kinetic energy is also 30J. 11) Kinetic energy is equal to the potential energy at lowest point so 12mv2 = mghv2 = 2ghv = 2*10*3v =60m/s

Spiderman, whose mass is 80.0 kg, is dangling on the free end of a 12.0-m-long rope, the other end of which is fixed to a tree limb above. By repeatedly bending at the waist, he is able to get the rope in motion, eventually getting it to swing enough that he can reach a ledge when the rope makes a 60.0 angle with the vertical. How much work was done by the gravitational force on Spiderman in this maneuver?

Explorers in the jungle find an ancient monument in the shape of a large isosceles triangle as shown in Figure P9.25. The monument is made from tens of thousands of small stone blocks of density 3 800 kg/m3. The monument is 15.7 m high and 64.8 m wide at its base and is everywhere 3.60 m thick from front to back. Before the monument was built many years ago, all the stone blocks lay on the ground. How much work did laborers do on the blocks to put them in position while building the entire monument? Note: The gravitational potential energy of an objectEarth system is given by Ug = MgyCM, where M is the total mass of the object and yCM is the elevation of its center of mass above the chosen reference level.

A hummingbird is able to hover because, as the wings move downward, they exert a downward force on the air. Newtons third law tells us that the air exerts an equal and opposite force (upward) on the wings. The average of this force must be equal to the weight of the bird when it hovers. If the wings move through a distance of 3.5 cm with each stroke, and the wings beat 80 times per second, determine the work performed by the wings on the air in 1 m if the mass of the hummingbird is 3.0 g.
