6. A long-jumper leaves the ground at an angle of 20.0° above the horizontaland at a speed of 11.0 m/s. (a) How far does he jump in the horizontaldirection? (Assume his motion is equivalent to that of a particle.)7. An astronaut on a strange planet finds that she can jump a maximumhorizontal distance of 15.0 m if her initial speed is 3.00 m/s. What is thefree-fall acceleration on the planet?8. A tire 0.500 m in radius rotates at a constant rate of 200 rev/min. Find thespeed and acceleration of a small stone lodged in the tread of the tire (on itsouter edge). (Hint: In one revolution, the stone travels a distance equal to thecircumference of its path, 2nr.)9. A student attaches a ball to the end of a string 0.600 m in length and thenswings the ball in a vertical circle. The speed of the ball is 4.30 m/s at itshighest point and 6.50 m/s at its lowest point. Find the acceleration of theball when the string is vertical and the ball is at (a) its highest point and (b)its lowest point.
