1) A ball is thrown vertically upward with a speed of 15 miles per hour. How long is it in the air? Assume it comes back to the same location and air resistance is negligible.

2) A car traveling at 70 km/hr into a building. The front end of the car compresses and the driver travels forward 1.2 m in coming to a stop. What is the average acceleration he experiences? express this acceleration in g's

3) Given a displacement vector with a magnitude of 5m, making an angle of 40 degrees counterclockwise from the positive y-axis. Draw the vector. Find its x and y-components.
