You throw a ball straight upward with an initial speed of 12 m/s. What is the objects acceleration on the way up and on the way down? Calculate the maximum height the ball can reach. What is the total flight time of the ball?
You throw a ball straight up, and it reaches a height of 22 m above your hand before falling back down. What was the speed of the ball just after it left your hand? m/s
From the top of a 70 m building, you throw a ball straight up at 6 m/s. The ball misses the building on the way down. What is the maximum height of the ball? What is the velocity of the ball after 2 s? What is the final velocity of the ball (just before it hits the ground) Now, the ball is thrown straight down at 6 m/s. What is the velocity of the ball after 2 s? Using the initial...
You throw a ball straight up from a rooftop. The ball misses the rooftop and eventually strikes the ground A mathematical model can be used to describe the relationship for the ball's height above the ground, y. after x seconds. x, seconds after the ball is y, ball's height, in feet, above the ground 289 271 214 on its way down thrown 3 4 2 a. Find the quadratic function y= - ax +bx + c whose graph passes through...
1. To find the height of an overhead power line, you throw a ball straight upward. The ball passes the line on the way up after 0.80 s, and passes it again on the way down 1.2 s after it was tossed. (a) What is the height of the power line? (b) What is the initial speed of the ball?
throw a ball straight up into the air with initial velocity vi. (neglect air resistance). how long will it take for the ball to come back to its initial position? what is the maximum height the ball reaches?
2) You throw a ball straight up with an initial velocity 15.0 m/s a) How high does it go? Ignor e the air resistance. (1 mark) b) How long does it take for the ball to reach its maximum height? (1 mark) What is the ball velocity when the ball is 6.00 m above the initial throwing point? c) (1 mark) What is the velocity of the ball when it back to initial point? (1 mark) d) 2) You throw...
5. You throw a ball straight up from the ground level to a height of 10 ft. The ball falls down and hits the floor. It then bounces back to a height that is 8 ft and repeatedly bouncing up and down indefinitely, each time reaching a height four-fifths of the previous height. (a) When the ball hits the ground the first time, we call this the first hit. Find the height of the ball on the fifth hit. (b)...
You throw a ball straight up from the ground (? = 0) with an initial speed of 20 m/s. At the same time (? = 0), another ball is dropped from a building that is 15 m high. How long will it take for the two balls to be exactly the same height off the ground?
You throw a ball straight up. The ball has an initial speed of 11.2 m/s when it leaves your hand. A) What is the maximum height the ball reaches relative to the throwing point. B) How long does it take the ball to reach this height? C) What is the position of the ball at t=2s? D) At what height does the ball have a speed of +5m/s?
