Standing on the roof of a 61 m tall building, you throw a ball straight up with an initial speed of 19.5 m/s. If the ball misses the building on the way down, how long will it take from you threw the ball until it lands on the ground below? Give your answer in seconds and round the answer to three significant figures.

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...
While standing on the roof of a building, a child tosses a tennis ball with an initial speed of 14 m/s at an angle of 35° below the horizontal. The ball lands on the ground 3.2 s later. How tall is the building?
While standing on the roof of a building, a child tosses a tennis ball with an initial speed of 12 m/s at an angle of 25° below the horizontal. The ball lands on the ground 3.3 s later. How tall, in meters, is the building?
You are on the roof of a tall building. Your TA (who is 1.8m tall) is walking by, and you drop (from rest at the level of the roof) a water balloon on him. It takes 2s for the balloon to go from the roof of the building to your TA's head. (a) How tall is the building? (b) What was the velocity of the balloon when it hit your TA? If instead of dropping the balloon from rest, you...
While standing at the edge of the roof of a building, you throw a stone upward with an initial speed of 7.39 m/s. The stone subsequently falls to the ground, which is 16.9 m below the point where the stone leaves your hand. At what speed does the stone impact the ground? How much time is the stone in the air? Ignore air resistance and take g -9.81 m/s. (This is NOT a suggestion to carry out such an experiment!)
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...
While standing at the edge of the roof of a building, you throw a stone upward with an initial speed of 7.15 m/s. The stone subsequently falls to the ground, which is 16.7 m below the point where the stone leaves your hand. At what speed does the stone impact the ground? How much time is the stone in the air? lgnore air resistance and take g-9,81 m/s. (This is NOT a suggestn to such an experimentt) Impact speed: Number...
A ball is thrown horizontally from the roof of a building 7.4 m tall and lands 9.4 m from the base. What is initial speed?
You throw a ball straight up, and it lands with 2/3 the speed with which you threw it. What fraction of the initial kinetic energy was lost during the time the ball was in the air?
Wile standing at the edge of the roof of a building, you throw a stone upward with an initial speed of 6.79m/s. the stone is subsequently falls to the ground, which is 12.1m below the point of where the stone leaves your hand. How much time is the stone in the air?
