Problem 1: The skiers leaves the ramp A at an angle of 20° with the horizontal. The ramp A is 10 ft above the snow. The skier needs to reach a distance of 300 ft to break is record. 1. Write the 6 equations of motion: acceleration, velocity and position on x and y during the free jump of the skier. 2. Find 2 equations to solve for V, and t. 3. Find the x and y components of velocity of the skier at B. 4. Find the Magnitude and angle of the velocity of the skier at B.

nt. 8. A cannonball is shot from a cannon at 45-degree angle: a. In Galeleo's Kinetic equations, which variable must be constant for the equations to give the correct results? b. If the x axis represents the horizonal axis, what is the value of ax? C. Assuming there was no air resistance, would final velocity of the cannonball be (1) greater than initial velocity, (2) less than initial velocity, or (3) the same as initial velocity when is at its maximum height? d. Assuming there was air resistance, would final velocity of the cannonball be (1) greater than initial velocity, (2) less than initial velocity, or (3) the same as initial velocity when is at its maximum height?

A car is driving along a circular track of diameter d = 0.75 km at a constant speed of v = 22 m/s.a. Write an expression for the magnitude of acceleration a of the car in terms of the given parameter. b. What is the magnitude, in meters per second squared, of the acceleration a of the car. c. Write an expression for the minimum coefficient of the friction μ between the car's tires and the road that is required in order to keep the car going in a circle in terms of the given parameters.

QUESTION 4 A skier leaves a ramp 20°-degree ramp with an initial velocity v from a height y above the horizontal ground. Calculate the maximum height, ymax, with respect to the horizontal ground that the skier reaches. Express your answer in meters to three significant figures. v = 20.1 m/s Yi = 18.7 m Ymax
