8) A 3.0 kg block slides along a frictionless horizontal surface with speed of 10.0 m/s, as shown below. After sliding a distance of 2.0 m, the block makes a smooth transition to a ramp with a kinetic friction coefficient u=0.38 inclined at an angle of 45° to the horizontal. What distance along the ramp does the block slide before coming momentarily to rest? 3.0 kg 10.0 m/s 450

The masses of the javelin, discus, and shot are 0.80 kg, 2.0 kg, and 7.2 kg, respectively, and record throws in the corresponding track events are about 98 m, 74 m, and 23 m, respectively. Neglecting air resistance, (a) calculate the minimum initial kinetic energies that would produce these throws, and (b) estimate the average force exerted on each object during the throw, assuming the force acts over a distance of 2.0 m. (c) Do your results suggest that air resistance is an important factor?

In an amusement park water slide, people slide down an essentially frictionless tube. The top of the slide is 3.0 m above the bottom where they exit the slide, moving horizontally, 1.2 m above a swimming pool. What horizontal distance do they travel from the exit point before hitting the water? Does the mass of the person make any difference?
In the figure, a runaway truck with failed brakes is moving downgrade at 107 km/h just before the driver steers the truck up a frictionless emergency escape ramp with an inclination of θ = 20°. The truck's mass is 1.4 × 104 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 L increase, decrease, or remain the same if (b) the truck’s mass is decreased and (c) its speed is decreased?
