11) An object slides on a level floor.It slows and comes to a stop with a constant acceleration of magnitude 2.4 m/s2What is the coefficient of kinetic friction between the object and the floor?.
12) The horizontal and vertical components of the initial velocity of a projectile fired above the horizontal are 16 m/s and20 m/s respectively. If there is no air resistance, how long does it take the projectile to reach the top of its trajectory?
13) An athlete competing in the long jump leaves the ground with a speed of 9.14 m/s at an angle of 55° with the vertical.What is the length of the athlete's jump if air resistance is of no significance?
