The number оf incidents оf sweаring оccurring in eаch of ten 5-minute intervаls is 2, 4, 0, 1, 1, 3, 2, 2, 5, 0. Using an interval recording procedure, the overall level of swearing calculated is:

Be sure tо shоw yоur work cleаrly аnd the equаtions you are using to solve each problem. You may not use derived equations if you do not show the derivation. All final answers should have the proper number of significant figures and include appropriate units. All problems are worth 12 pts. 21) A 42.0 kg child starts at rest and slides down a 8.0 m long water slide that is 5.0 m high. The coefficient of kinetic friction is 0.30 and there are no other drag forces present. (12 points) a) Draw a pictorial diagram with values and free body diagram b) What is the child's acceleration? c) How much work is done by gravity? 22) Two brothers, Joe and Sam are riding scooters toward each other. Joe, the scooter and a backpack have a total mass of 45.0 kg and are moving to the right with a speed of 2.00 m/s. Sam and his scooter have a mass of 35.0 kg and are moving to the left with a speed of 1.75 m/s. As the brothers pass each other, Joe throws the 1.5 kg backpack to Sam with a velocity of..................................... (12 points) a) Draw a pictorial diagram with values labeled of the scenario. b) Neglecting any friction effects, what is Joe's new velocity after he throws the backpack to Sam? c) Neglecting any friction effects, what is Sam's new velocity after he catches the backpack? 23) A wagon is pulled along a horizontal sidewalk. A force of 145 N is applied to the handle of a wagon that makes an angle of 25.0° from the horizontal. The brakes on the wagon are locked so that its wheels slide rather than roll. The wagon has a mass of 42.0 kg, and an acceleration of 0.75 m/s2. a) Draw a pictorial diagram with values labeled and a free body diagram for the wagon. b) What is the coefficient of kinetic friction between the sliding wheels and the ground? 24) A Nerf gun with a 13.0 cm barrel is used to horizontally launch a 8.5 g plastic ball. The spring is compressed 9.0 cm as the ball is pushed into the barrel. When the trigger is pulled, the spring is released and the ball leaves the barrel with a velocity of 3.15 m/s. Assume that a constant frictional force of 0.052 N acts on the ball as it moves through the barrel. (12 points) a) Draw a pictorial diagram with values labeled. b) What is the spring constant of the Nerf gun? 25) A student swings a stopper attached to a string in a horizontal circle above their head.  The stopper has a mass of 22.52 g and the string has a length of 42.0 cm.  The stopper starts at rest and reaches a rate of rotation of 95 rev/min in 25 s. a) Draw a pictorial diagram with values labeled and name of the force that causes the stopper to move in a horizontal circle? b) What is the angular velocity? c) What is the centripetal acceleration? d) What is the centripetal force?
