A basketball rolls onto the court at a speed of 4.0 m/s to the right and slows down with a constant deceleration of 0.50 m/s^2 over a distance of 14 m. What is the velocity of the basketball after rolling for 14 m?
The largest asteroid, ceres, has a radius 0.073 times the radius of earth and a mass of 0.0002 earth masses. How much would a 72 kg astronaut weigh in ceres in pounds?

A golf ball is dropped from a height of 9.5m. It hits the pavement and bounces back up, rising 5.7m before falling back down. A boy catches the ball on the way down when it is 1.20m above the pavement. Ignoring air resistance, calculate the total time the ball is in the air, from drop to catch.

If an ant starts at 0 radians and travels to 4.5 radians in 18 seconds, what is its angular velocity? If the ant then slows to 0 rad/s in 3 seconds, what is its angular acceleration?
What is the mass of an object that has a density of 1.3 g/cm^3 and a volume of 2cm^3
Distance vs Displacement As an object moves, its location undergoes change. There are two quantities that are used to describe the changing location. One quantity - distance accumulates the amount of total change of location over the course of a motion. Distance is the amount of ground that is covered. The second quantity - displacement - only concerns itself with the initial and final position of the object. Displacement is the overall change in position of the object from start to finish and does not concern itself with the accumulation of distance traveled during the path from start to finish. True or False: An object can be moving for 10 seconds and still have zero displacement. A. True B. False
