1) A golfer is going to hit a ball across horizontal ground at an initial angle of 24.4 degrees to the horizontal. If he wants the ball to travel a distance of 176 m before it hits the ground, what should the initial speed of the ball be, in units of m/s?

2)An object moves107m South,then 137m West, and finally 215m North. If the total time taken was 300s,What was the average speed for the complete journey, in units of m/s?

3)What is the angular velocity, in units of rad/s, of a point on an objectmoving with uniform circular motion with a Period of 0.61s?

4)The motor of a washing machinerotates with a period of 24.3 ms.What is the angular speed,in units of rad/s?

5)The end of an electric drill (the bit)is initially at rest.It then has a constant angular acceleration of 217rad/s². How much time will it take for the angular speed of the bit to be 632 rad/s, in units of seconds?

6)On a wet day a car can travel around a horizontal corner of radius 67m without slippingwith a maximum speed of 15m/s.What is the coefficient of static friction between the car tires and the road?

7)A 2 500?kg truck moving at 10.00 m/s strikes a car waiting at a traffic light, hooking bumpers. The two continue to move together at 7.00 m/s. What was the mass of the struck car?

8)A man uses a spanner of length (d) = 0.280 m to attempt to loosen a nut. He applies a force (F) at an angle ? = 38.0 ⁰, as shown in the diagram. If a torque of magnitude 55 Nm is required to loosen the nut, what is the magnitude of the force that he must apply, in units of newtons

9)An object (M) of mass 10.8 kg is free to rotate about an axis a distance (R) of 0.359 m from its center, as shown in the diagram. What will the angular momentum of the object be if it is rotating with an angular speed of 2.24 rad/s, in units of kg.m²/s?
