Q1. Mass M1 (5.48 kg) is on a rough inclined plane that makes an angle θ = 43.7o with the horizontal. The coefficient of kinetic friction between M1 and the incline is μk = 0.137. A rope is attached to M1, passes over a frictionless pulley, and is attached to mass M2 = 8.37 kg which hangs freely.
HINT: In each part: consider the direction in that m1 tends to move to conclude the direction in which the friction is acting.
a) If M1 is at first moving up the incline: find the magnitude of the acceleration of the masses.
b) If M1 is at first moving down the incline: find the magnitude of the acceleration of the masses.
Q2. Volcanoes on the Earth eject rocks at speeds of up to 160 m/s. Consider a 1260 m high volcano that ejects rocks in all directions. What is the maximum height above sea level reached through rocks?
Find out the mutual inductance per unit length between two long solenoids, one inside the other, whose radii are r_1 and r_2 and whose turns per unit length are n_1 and n_2.
Speedboat A negotiates a curve whose radius is 115 m. Speedboat B negotiates a curve whose radius is 194 m. Each boat experiences the same centripetal acceleration. What is the ratio vA/vB of the speeds of boats.
A uniform solid sphere of radius 0.503 m and mass 15.7 kg turns counter clockwise (when viewed from above) about the vertical axis through its center. Find its vector angular momentum when its angular speed is 3.08 rad/s. Wouldn't you use the formula..
The sport with the fastest moving ball is jai alai, where measured speeds have reached 303km/h. If a professional jai alai player faces a ball at that speed and involuntarily blinks, he blacks out the scene for 100ms. How far does ball move throughou..
A point P is on a rim of a wheel of radius 2.0m. At time t=0 wheel is at rest and P is on the x-axis. The wheel undergoes a uniform angular acceleration of 0.01 rad/s2 about the center O. Find out the time t, when P returns to an original position on..
How to find out the magnitude of the acceleration
A hawk is flying horizontally at 17.0m/s in a straight line, 160 m above the ground. A mouse it has been carrying struggles free from its grasp. The hawk continues on its path at the same speed for 2.00s before attempting to retrieve its prey.
A plate carries a charge of -3.9 µC, while a rod carries a charge of +2.2 µC. How many electrons should be transferred from the plate to the rod, so that both objects have the same charge.
One mole of nickel (6E23 atoms) has a mass of 54 grams, and its density is 8.9 grams per cubic centimeter. You have a long thin bar of nickel, 2.0 m long, with a square cross section, 0.12 cm on the side.
Hakeem throws an 8.50 g ball straight down from a height of 2.0 m. The ball strikes the floor at the speed of 7.5 m/s. What was the initial speed of the ball? Suppose that air resistance is negligible.
A bartender slides a beer mug at 1.30 m/s towards a customer at the end of a frictionless bar that is 2.0m tall. The customer makes a grab for the mug and misses, and the mug sails off the end of the bar.
Two boats start together and race across a 46 km wide lake and back. Boat A goes across at 44 km/h and returns at 48 km/h. Boat B goes across at 27 km/h, and its crew, realizing how far behind it is getting, returns at 69 km/h. Turnaround times are n..
