You are driving in your car and have just purchased a tray of drinks which are sitting on the flat seat next to you. If you are travelling at 15.0 m/s and approach a turn with a radius of 30.0 m, what minimum coefficient of static friction is necessary to keep the drinks from sliding?
A model airplane is flying in a circular loop in the vertical plane, with a radius of 80.0 m. What is the minimum speed that the airplane can maintain without being forced out of the loop?
A 5.0 kg cart on a table is connected to a string that hangs over pulley suspending a 3.0 kg block over the side of the table. Determine the acceleration of the system, as well as the tension in the string. (6 marks)
A 70.0 kg weight sits at the top of a ramp that makes an angle of 40o with the horizontal. As the weight slides down the ramp, it experiences a force of friction of 75 N. What is the acceleration of the weight down the ramp?
A football with a mass of 0.4 kg is thrown with a force of 60.0 N. Discounting friction, what is the acceleration of the ball?
You are on serve in a ping pong match and serve the ball at an angle of 42o above horizontal, 15.0 cm above the end of the table, with a velocity of 6.0m/s. (8 marks total)
a) What is the time of flight? (2 marks)
b) What is the horizontal distance travelled? (1 mark)
c) What is the velocity on impact? (1 mark)
d) If the net is also 15.0 cm high, and 174.0 cm from the edge of the table, will the ball clear the net?
A ball is thrown horizontally from the roof of a 20.0 m high building and lands 10.0 m away from the base of the building. Determine initial and final velocity.
a thermometer with an arbitrary scale, s, of equal division registers -30°S at the ice point and 90°S at the steam point. Calculate the celsius temperature corresponding to 60°S
A riverboat crosses the river going due north at 8m/s crosses a river going due east at 6m/s. If it takes the boat 18s to cross the river, how far downstream did the boat drift?
