1. A motorcycle is travelling horizontally at 18 m/s when it reaches the edge of a 63 m high cliff. At what velocity does the motorcycle hit the ground? 2. A boat heads [N] at a speed of 12 m/s relative to the water. The water flows at a rate of 4.0 m/s [W] relative to the shore. What is the velocity of the boat relative to the shore? 3. A cannonball is fired horizontally from a cannon at a speed of 45 m/s from the edge of a 125 m high cliff. How far from the base of the cliff does the cannonball land on the level ground below? 4. Dick kicks a soccer ball off the ground at an angle. The soccer ball rises to a maximum height of 3.8 m before returning to the ground, 25 m directly in front of Dick. At what velocity does Dick kick the soccer ball? 5. A woman pushes down on the handle of lawnmower with a force of 150 N. The handle makes an angle of 35 with the horizontal. The lawnmower has a mass of 15 kg. The coefficient of friction between the wheels and the ground is 0.50. Find the magnitude of the acceleration of the lawnmower. 6. A 5.0 kg block on a 33 incline is attached to a 2.0 kg block by a light string as shown below. The pulley is frictionless, however there is a 0.10 coefficient of friction between the 5.0 kg block and the incline. Find the acceleration of the 2.0 kg block. 5.0 kg 2.0 kg 7. A conical pendulum consists of a 0.50 kg ball attached to a string with a length of 75.0 cm. The ball travels at a constant speed in a circle, while the string makes an angle of 32 with the vertical. What is the speed of the ball? 32 ANSWERS TO REVIEW 1 39 m/s [ 63 to the ground] 11 5.9 x 103 m/s 2 13 m/s [N 18 W] 12 17 cm 3 2.3 x 102 m 13 8.7 x 103 m/s 4 17 m/s [310 up from ground] 14 6.4 x 10-13 C 5 0.42 m/s2 15 2.3 h 6 0.43 m/s' [up] 16 6.7 x 10' N/C [E 70'S] 7 1.6 m/s 17 480 nm 8 1.4 x 103 N 18 1.3 x 105 m 9 39% is lost 19 1.9 x 104m 10 2.2 m 20 1.1 x 10 m CamScanner
