Q1. A 5.00--long ladder has mass 12.5 kg and is leaning against a frictionless wall, making a 64 degree angle with the horizontal. If the coefficient of friction between the ladder and ground is 0.42, what is the mass of the heaviest person who can safely ascend to the top of ladder?
Q2. A shell is fired from the ground with an initial speed of 1.70*10^3 m/s at an initial angle of 55° to the horizontal.
(a) Neglect air resistance; find the shell's horizontal range.
(b) Find the amount of time shell is in motion.
What is the gauge pressure of the water at the pump? Suppose steady, laminar flow of water, no viscosity, and no air drag on the water jet. The acceleration of gravity is 9.81 m/s2.
If you now place a pencil under the edge of the mirror nearer the wall, tilting it upward by 5.0, how much higher on the wall is the spot?
Use this technique to find formula for the intensity of a sound, in terms of sound level and the reference intensity. There will be a quantity involved in the calculations. When you enter your answer, leave off the unit.
James is scheduled for a job interview with Ms. Farrar. He knows that she is in charge of selecting, placing, and evaluating employees for her firm, but he cannot remember her educational background. Which is most likely Ms. Farrar's educational back..
A shell, fired from a cannon, has a muzzle speed (the speed as it leaves the barrel) of 800 ft/s. The barrel makes an angle of 45o with the horizontal and, for ease; the barrel opening is assumed to be at ground level.
A tennis ball is thrown toward a vertical wall with a speed of 22.0 m/s at the angle of 40.0° above the horizontal. The horizontal distance between the wall and the point where the tennis ball is released is 28.0 m.

Speedboat A negotiates a curve whose radius is 150 m. Speedboat B negotiates a curve whose radius is 190 m. Each boat experiences the same centripetal acceleration. What is the ratio vA/vB of the speeds of boats.
A ranger in a national park is driving at 52 km/h when a deer jumps onto the road 86 m ahead of the vehicle. After a reaction time of t s, the ranger applies the brakes to produce an acceleration of -2.9 m/s2.
