- In the figure, a runaway truck with failed brakes is moving downgrade at 109 km/h just before the driver steers the truck up a frictionless emergency escape ramp with an inclination of 0 = 17°. The truck's mass is 1.3 × 10ª kg. (a) What minimum length L must the ramp have if the truck is to stop (momentarily) along it? (Assume the truck is a particle, and justify that assumption.) Does the minimum length Lincrease, decrease, or remain the same if (b) the truck's mass is decreased and (c) its speed is decreased? (a) Number i 1.6 Units m (b) remain the same (c) decreaseProfessional baseball pitchers deliver pitches that can reach the blazing speed of 100 mph (miles per hour). A local team has drafted an up-and-coming, left-handed pitcher who can consistently pitch at 41.12 m/s (92.00 mph). Assuming a pitched ball has a mass of 0.1422 kg and has this speed just before a batter makes contact with it, how much kinetic energy does the ball have? Kball= Recall that the acceleration due to gravity is 9.81m/s2. How high would the ball need to be dropped from to attain the same energy as it did when it was pitched (neglect air resistance)? hball=A car is bumper is designed to withstand a 4.32-km/h (1.2-m/s) collision with an Immovable object without damage to the body of the car.

The box of mass m, is released from rest at height h above the table. Use the isolated system model to answer the following. (We assume m, > m,. Use any variable or symbol stated above along with the following as necessary: g.) (a) Determine the speed of m, just as m, hits the table. v= 5.77 Since the only force acting is the conservative force of gravity, mechanical energy is conserved. Write a statement of conservation of energy and the expressions for the change in kinetic energy and the change in gravitational potential energy. Combine these three expressions and solve for the speed in terms of known quantities. Note that you want the speed and not the velocity.

- A 0.450 kg ball of Play-Doh hangs from the ceiling by a string. A 0.0850 kg wad of Play-Doh is thrown straight upward from below the ball and strikes the ball with a speed of 5.60 m/s and sticks to it. (a) Is the mechanical energy of this system conserved? Yes No (b) How high (in cm) does the combined mass of Play-Doh rise above the original position of the ball of Play-Doh? X Since the collision takes place over a very short time interval, we may conserve linear momentum to obtain the speed of the combined mass right after the collision. Knowing the speed of the combined mass the instant after the collision, see if you can use your knowledge of kinematics to determine how high the combined mass rises above the original position of the ball of Play-Doh. cmNeeds Complete typed solution with 100 % accuracy.A Box of mass 1.2 kg is dropped from a window. the box starts from rest (inital speed 0).
