- Billy launches a tennis ball with a sling shot at an angle of 62 degrees above the horizontal at a speed of 45 meters per second . The tennis ball lands in a nearby tree. How far away is the tree?8. You fire a ball with an initial speed of v at an angle o above the surface of an incline, which is itself inclined at an angle e above the horizontal. a) Find the distance, measured along the incline, from the launch point to the point when the ball strikes the incline. b) What angle o gives the maximum range, measured along the incline? Ignore air resistance.(p) 6) A projectile is fired from ground level with a speed of 80 m/s at an angle 60° above the horizontal on an airless plane where g = 10.0 m/s2. What is the horizontal component of its velocity after 4.0 s?
- A projectile is fired from a point 50 meter from a tall cliff at 75 m/sec and at angle of 50 degrees above the horizontal. It will strike the cliff at a point h above the cliff base. What is h? What is the final speed of the projectile when it hits the cliff in the problem above?A crazy, young boy on a sled is able to get up to an incredible speed of 22.5 m/s (yes, he is wearing a helmet!)along a frictionless horizontal surface while he approaches an icy hill with a vertical height of 11 m, as shown.He makes it to the top, and then fies of horizontally from the ledge of the hill. How far from the base of thehill does the boy land?An arrow is aimed horizontally, directly at the center of a target 24.0 m away. The arrow hits 0.060 m below the center of the target. Neglecting air resistance, what was the initial speed of the arrow in m/s?
- 5a helicopter flying with a constant horizontal speed of 25.9 m/s at the height of 170 m drops a packet that lands over a football field. what will be the speed of the packet at the landing? Neglect air resistance and use g=9.80 m/s2In a friendly game of handball, you hit the ball essentially at ground level and send it toward the wall with a speed of 26 m/s at an angle of 32∘ above the horizontal.How high is the ball when it hits the wall?
