Two seconds after the elevator begins to move, a man standing 12 m above the initial position of the top of the elevator throws a ball upward with an initial velocity of 20 m/s. Determine when the ball will hit the elevator.

- An inflatable raft (unoccupied) floats down a river at an approximately constant speed of 3.9 m/s. A child on a bridge, 66 m above the river, sees the raft in the river below and attempts to drop a small stone onto the raft. The child releases the stone from rest. In order for the stone to hit the raft, what must be the horizontal distance between the raft and the bridge when the child releases the stone?While exploring the canopy of the rainforest in equatorial South America, Anastasia falls from a branch 35.0 meters high. Exactly 1.3 seconds later Joe falls from the same branch. How high above the ground is Joe when Anastasia splats into the mud below? (the mud is very squishy and nobody is injured)A catapult launches a test rocket vertically upward from a well, giving the rocket an initial speed of 80.4 m/s at ground level. The engines then fire, and the rocket accelerates upward at 3.80 m/s2 until it reaches an altitude of 1030 m. At that point its engines fail, and the rocket goes into free fall, with an acceleration of −9.80 m/s2. (You will need to consider the motion while the engine is operating and the free-fall motion separately.) (a) For what time interval is the rocket in motion above the ground? Your response differs from the correct answer by more than 10%. Double check your calculations. s(b) What is its maximum altitude? Your response differs from the correct answer by more than 10%. Double check your calculations. km(c) What is its velocity just before it hits the ground? m/s
- 1b. A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of v0 = 18.5 m/s. The cliff is h = 20.0 m above a flat, horizontal beach as shown in the figure. What are the components of the initial velocity? v0x = ____m/s v0y = ____m/sA soccer ball is kicked from the ground with an initial speed of 19.5 m/s at an upward angle of 44.3°. A player 53.7 m away in the direction of the kick starts running to meet the ball at that instant. What must be his average speed if he is to meet the ball just before it hits the ground? Neglect air resistance. Use g=9.81 m/s². Number i UnitA soccer ball is kicked from the ground with an initial speed of 18.9 m/s at an upward angle of 48.1. A player 48.4 m away in the direction of the kick starts running to meet the ball at that instant. What must be his average speed if he is to meet the ball just before it hits the ground? Neglect air resistance.Use g-9.81 m/s². Number 4.32 Unit m/s
- In a circus act, an acrobat rebounds upward from the surface of a trampoline at the exact moment that another acrobat, perched 9.0 m above him, releases a ball from rest. While still in flight, the acrobat catches the ball just as it reaches him. If he left the trampoline with a speed of 8.0 m/s, how long is he in the air before he catches the ball?A soccer ball is kicked from the ground with an initial speed of 20.2 m/s at an upward angle of 40.9*. A player 52.8 m away in the direction of the kick starts running to meet the ball at that instant. What must be his average speed if he is to meet the ball just before it hits the ground? Neglect air resistance.Use g=9.81 m/s?. Number i UnitI had a dream last night that I was chased by my teddy bear. In my dream, I was sleepwalking at a constant velocity of 60ft/sec. At exactly 4:00 am I noticed my teddy bear standing 1000 feet behind me. At that instant I began to accelerate at 10 ft/sec/sec and the teddy bear began to accerlate after me at 12 ft/sec/sec. At the moment the bear caught up to me, I woke from my dream in a cold sweat. To the nearest second, What time was this?
- After a constant acceleration of 3.52 m/s/s at 9.6 degrees above the +x-axis is applied by the motors of a boat for 7.05 seconds, the boat is moving at 96.8 m/s at 34 degrees above the +x-axis. What was the displacement of the boat during this time? What is the angle from the positive x-axis?A skateboarder decides to try to jump from the top of a set of stairs and land at the bottom.

One student throws a ball (ball 1) vertically downward at 13.1 m/s; at the same instant, the other student throws a ball (ball 2) vertically upward at the same speed. The second ball just misses the balcony on the way down. (a) What is the difference in the two ball's time in the air? (b) What is the velocity of each ball as it strikes the ground?
