6. A ball rolls down the inclined surface shown here. It starts from rest and accelerates down the 4.00-meter incline at a constant rate 2.00 m/sa. The ball then falls off the edge of the surface and travels like projectile until it hits the ground. (a) What are the balls velocity components at the moment it leaves the inclined surface? (b) At what horizontal distance from the base of the surface does the ball land? (c) What is the total amount of time the ball is in motion? 7. A student decides to measure the speed of a ball launched from a projectile launcher, like the one shown here. She points the launcher toward the wall at an angle of 30 to the horizontal. She then places a target on the vertical wall, a distance of 2.0 meter from the launcher. The launcher is set 1.5 m above the ground. If the ball hits the target 1.1 m above the ground, determine the initial speed of the ball. 8. Known throughout Ursuline for her adventurous motorcycle jumps, Catie Croker is attempting her most daring feat yet. She is going to ride up a 15.0 slope and then jump over 10.0-meter wide "Thunder Canyon." 15.00 Thunder Canyon Now Catie may be fearless, but she is never reckless. She knows she must precisely calculate the exact minimum speed necessary to clear the canyon. What is that minimum speed
