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
You throw a ball vertically upward with a velocity of 10 m/s from a window located 20 m above the ground. Knowing that the acceleration of the ball is constant and equal to 9.81 m/s^2 downward, determine (a) the velocity v and elevation y of the ball above the ground at any time t, (b) the highest elevation reached by the ball and the corresponding value of t, (c) the time when the ball hits the ground and the corresponding...
You throw a ball vertically upward with an initial speed of 5 m/s from your dorm window... QUESTION 6 5 p You throw a ball vertically upward with an initial speed of 5 m/s from your dorm window. If the window is 10 m above the ground, find the time the ball is in flight. Give your answer with three significant figures and do not write the units. 5 p. QUESTION 7 Continuing with exercise 6, calculate the speed of...
Two students are on a balcony 19.1 m above the street. One student throws a ball vertically downward at 13.8 m/s. At the same instant, the other student throws a ball vertically upward at the same speed. The second ball just misses the balcony on the way down. What is the magnitude of the velocity of the first ball as it strikes the ground? Answer in units of m/s. What is the magnitude of the velocity of the second ball...
You throw a ball upward with an initial speed of 3.0 m/s from an initial height of 1.5 m. After you throw the ball, its acceleration is 9.81 m/s2 downward. Taking upward to be the positive direction, write the position-time equation for the ball's motion. Express your answer in terms of t. t is expressed in seconds.
