- Dave with a mass of 60 kg goes tubing down a 20 m long hill that has an angle off the horizon of 25º. (Gravity applies) a. He gets a push from the bottom of the hill, so his initial velocity is 2 m/s. How far up the hill will he go before stopping? (there’s no friction) b. He goes back down the hill and then his friend Jill tries to pull him on the tube across a small patch of grass (μk=0.30). If she is pulling parallel to the ground at constant 5 m/s for 5 sec how much power does she expend? c. After climbing back uphill, Dave decided to roll down the hill instead. If he were to be a long cylinder with a radius of 0.1 m, what is his moment of inertia? d. After rolling without slipping down the hill, what is Dave’s final velocity at the bottom of the hill? What is his angular velocity at the bottom of the hill? Dave with a mass of 60 kg goes tubing down a 20 m long hill that has an angle off the horizon of 25º.

(Hint: Since the force is going opposite of the car, then the force must be negative). How long does it take for the car to come to a complete stop? GU E SSSupposed a 52.5kg gymnast is climbing a rope. What is the tension in the rope, in newtons, if he climbs at a constant speed?
- s seen in Figure 1, a 63.2 kg glacier climber finds herself dangling over theedge of an ice cliff. Fortunately, she’s connected by a rope of negligible mass to a 1220kg rock located 48.6 m from the edge of the cliff, and help is on the way. Unfortunately,the ice is frictionless so she accelerates downward. What’s her acceleration and howmuch time does she have before the rock goes over the cliff?A box with mass m sits at the bottom of a long ramp thatis sloped upward at an angle a above the horizontal. You give the boxa quick shove, and after it leaves your hands it is moving up the rampwith an initial speed v0. The box travels a distance d up the ramp andthen slides back down. When it returns to its starting point, the speedof the box is half the speed it started with; it has speed v0 /2. What isthe coefficient of kinetic friction between the box and the ramp? (Youranswer should depend on only a.)A child of mass 26 kg , is sliding down a water-slide that has an angle of 32 deg. If the water lubricates the slide to a frictionless surface, and the slide is 9 meters long. What is the child's velocity at the bottom?

- An object with a mass of 1.76 kg is initially at rest upon a horizontal, frictionless surface. An applied force of 3.04 N i acts on the object for 2.08 s. What is the object's final speed? Enter a number rounded to 2 decimal places and assume the answer has proper SI Units.Q3. A roller-coaster car, whose mass is1000 kg, starts from rest (y=40 m). Itreaches a vertical height of only 25 m onthe second hill, where it stopsmomentarily. Calculate the thermalenergy produced by friction forces andestimate the average friction force(assume it is roughly constant) on the car,if the roller-coaster car travelled a totaldistance of 400 m.on is 11. A string can hold up 12 kg without breaking. You tie the string to a 30 kg object sitting on ice and use it to pull the object horizontally for 22 m.
