His motion through space can be modeled precisely as that of a particle at his center of mass, which we will define in Chapter 9. His center of mass is at elevation 1.02 m when he leaves the floor. It reaches a maximum height of 1.85 m above the floor and is at elevation 0.900 m when he touches down again. Determine (a) his time of flight (his hang time), (b) his horizontal and (c) vertical velocity components at the instant of takeoff, and (d) his takeoff angle. (e) For comparison, determine the hang time of a whitetail deer making a jump (Fig. P4.12b) with center of mass elevations yi = 1.20 m, ymax = 2.50 m, and yf = 0.700 m.

- **19. ssm A 325-kg boat is sailing 15.0° north of east at a speed of 2.00 m/s. Thirty seconds later, it is sailing 35.0° north of east at a speed of 4.00 m/s. During this time, three forces act on the boat: a 31.0-N force directed 15.0° north of east (due to an auxiliary engine), a 23.0-N force directed 15.0° south of west (resistance due to the water), and Fw (due to the wind). Find the magnitude and direction of the force Fw. Express the direction as an angle with respect to due east.arrow_forwardA 50-kg cart is rolling across the floor with an initial speed of 4 m/s toward a glass window which is 5 m away.

You step in front of the cart and push against the motion. You will find what force you need to push in order to stop the cart in a distance of 5 m. what is the net force? what is the force of friction on the cart? what is the force of the push?arrow_forwardYou and a friend are on a road trip when your car runs out of gas only 20 meters from a gas station fortunately you're in Montana so the road is perfectly horizontal. You put the car in neutral and apply a horizontal force of 455 N, while your friend applies a horizontal force of 585 N in the same direction. The cars mass is m= 1600kg. The car begins to move, and you push the car to the pump. The car started from rest when you and your friend began pushing.
