1. List (by number and name) and define with words or equations each of Newton's Laws governing linear motion. Give a real life example illustrating each.
2. A person performs a standard long jump from the ground (takeoff and landing surfaces the same). Using a total flight time of 0.43 s and a horizontal
displacement of 2.5 m, calculate the following.a. Vertical velocity at takeoff.b. Horizontal velocity at takeoff.c. Actual (resultant) velocity at takeoff.d. Angle of takeoff.e. Peak height.
3. Identify five examples of torque in human activity, and identify the force and moment arm associated with the torque.
