Q1. What is the terminal speed for an 84.00 skier going down a 38.0 degree snow-covered slope on wooden skis = 0.06? Assume the skier is 1.70 m tall and 0.500 m wide.
Q2. A 10.00 g bullet is fired horizontally into a 107 g wooden block that is at first at rest on a frictionless horizontal surface and connected to a spring of constant 148 N/m. The bullet becomes embedded in the block. If the bullet-block system compresses the spring by the maximum of 74.00 cm, what was the speed of bullet at impact with the block?
What are direction and magnitude of total velocity
What friction torque is necessary to reduce its angular speed from 90.0 {rm rpm} to 45.0 {rm rpm} in a time interval of 32.0 {rm s}.
An object is lifted vertically 2m and held there. If the object weighs 30N, how much work was done in lifting it. Describe it briefly.
A stone has a mass of 6.0 x 10-3 kg and is wedged into the tread of an automobile tire, as the drawing shows. The coefficient of static friction between the stone and each side of the tread channel is 0.90.

How to find the magnetic field
A cube of ice is taken from the freezer at -8.0 and placed in a 113 aluminium calorimeter filled with 306 of water at room temperature of 20.0. The final situation is observed to be all water at 15.0.
A baseball is bunted down the third-base line leaving the bat from a height of 0.850m with an initial velocity of 4.00m/s at an angle of 37.87° above horizontal.
At what angle of incidence will green light (g = 560 nm) be most strongly reflected? Imagine the film has the minimum thickness that can produce these reflections.
A basketball player makes a jump shot. The 0.600 kg ball is released at a height of 2.00 m above the floor with a speed of 7.20 m/s. The ball goes through the net 3.10 m above the floor at a speed of 4.20 m/s Find the work done on the ball by air ..
