You throw a ball straight down from an apartment balcony to the ground below. The ball has an initial velocity of 5.35 m/s, directed downward, and it hits the ground 2.12 s after it is released. Find the height of the balcony.
You throw a ball vertically from an apartment balcony to the ground 13.6 m below. Find the ball's initial velocity if it hits the ground 1.08 s after you release it. magnitude? direction? ---Select--- upward downward
Jenny throws a ball straight down from the balcony of an apartment building at a velocity of 8.38 m/s. Calculate the velocity (m/s) of the ball after 1.12 s. Neglect air resistance.
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...
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)...
Standing on a balcony, you throw your keys to a friend standing on the ground below. 1.1 seconds after you release the keys, they have an instantaneous velocity of 15.4 m/s, directed 52deg below the horizontal. What initial velocity did you give them? Magnitude? Direction?
Standing on a balcony, you throw your keys to a friend standing on the ground below. 1.2 seconds after you release the keys, they have an instantaneous velocity of 15.7 m/s, directed 53° below the horizontal. What initial velocity did you give them? magnitude direction (below the horizon)
Standing on a balcony, you throw your keys to a friend standing on the ground below. 1.3 seconds after you release the keys, they have an instantaneous velocity of 15.6 m/s, directed 55° below the horizontal. What initial velocity did you give them? magnitude direction below the horizon
Standing on a balcony, you throw your keys to a friend standing on the ground below. 1.2 seconds after you release the keys, they have an instantaneous velocity of 14.0 m/s, directed 58° below the horizontal. What initial velocity did you give them? magnitude direction below the horizon
