(a) How long would it take a 1.50105kg airplane with engines that produce 100 MW of power to reach a speed of 250 m’s and an altitude of 12.0 km if air resistance were negligible? (b) If it actually takes 900 s, what is the power? (c) Given this power, what is the average force of air resistance if the airplane takes 1200 s? (Hint: You must find the distance the plane travels in 1200 s assuming constant acceleration.)
1. You are conducting an experiment to find the kinetic coefficienct of friction between a 5kg box and a ramp. The ramp has an angle of 25° above the horizontal. You start the box from rest. release it. and let it slide down the ramp. a) If the box starts at a height of 1 meter above the ground. what is the theo- retical value of its velocity at the bottom of the ramp? b) When you do the experiment, you find that the experimental value of the final velocity is 3.5 m/s. How much mechaical energy was “lost”? c) Assume that all of the mechanical energy 'lost' in part b) was due to Friction. Draw a free-body diagram. and determine the magnitude of the Normal Force acting on the box. d) Using the Normal force, determine the co-efficient of friction between the box and the ramp, if the system lost the amount of energy you caculated in part b). Hint: Use the work done by friction.

A block slides down a smooth ramp, starting from rest at a height h. When it reaches the bottom it’s moving at speed ν. It then continues to slide up a second smooth ramp. At what height is its speed equal to ν/2?A. h/4 B. h/2 C. 3h/4 D. 2h
Computation. A block is released from rest at the top of a 47-m long frictionless ramp inclined at 34° above the horizontal. What is the block's speed at the bottom of the ramp? v= m/s Record your numerical answer below, assuming three significant figures. Remember to include a "-" if/when necessary.
Lhte In 2012, Austrian skydiver, Felix Baumgartner, set a record for the highest exit altitude of 127 852 feet. He jumped from a helium balloon located in the Earth's stratosphere (see figure). At that altitude the atmosphere is too thin to breathe, so Baumgartner wore a special pressurized suit. During his free fall toward the earth, he reached a maximum speed of 843.6 mph, which is greater than the speed of sound. This set a record for greatest speed achieved during free fall and also set off a small sonic boom heard by his friends and family on the ground. Assume the effect of air resistance can be neglected and the acceleration due to gravity remains constant during his fall with a value of 9.807 m/s² and calculate the distance he fell before reaching 843.6 mph.

13. A block slides along a track with an initial velocity vo = 7.0 m/s from one level to a higher level after passing through an intermediate valley. The difference h from the initial position to the elevated track is 0.89 m. The track is frictionless until reaches the top. What is the velocity of the block when it reaches the top of the track?
