An elevator without a ceiling is ascending with a constant speed of 11 m/s. A boy on the elevator shoots a ball directly upward, from a height of 2.1 m above the elevator floor, just as the elevator floor is 24 m above the ground. The initial speed of the ball with respect to the elevator is 18.7 m/s. (a) What maximum height above the ground does the ball reach? (b) How long does the ball take to return to the elevator floor?

A cannon is mounted on a tower above a wide, level field. The barrel of the cannon is 80 m above the ground below. A cannonball is fired horizontally with an initial speed of 800 m/s. Assuming air resistance can be neglected, approximately how long will the cannonball be in flight before it hits the ground? О 16 s 40 s 4 s 32 s 2 s About how far from the base of the tower will the cannonball land? 3000 m 800 m O 160 m 40 m 60000 m
A Supply plane needs to drop a package of food to scientists working on a glacier in Greenland. The plane flies 97 m above the glacier at a speed of 133 m/s. How far away from the target should it drop the package? (Hint: This is a horizontal projectile. The package has the same initial speed as the plane)
A person sitting on the ground floor of a building notices through the window, of height 1.5 m, a ball dropped from the roof of the building and crosses the window in 0.1 s. What is the velocity of the ball when it is at the topmost point of the window? (g-10 m/s²) (1) 20 m/s (2) 15.5 m/s (3) 14.5 m/s (4) 4-5 m/s
Two students are on a balcony 18.6 m above the street. 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?
An airplane needs to drop a package of supplies to a team in a remote location (landing is not possible). The plane is flying 112.8 m above the ground at a speed of 196.8 m/s. We know that the plane should NOT drop the package when it is passing directly over the location. Instead, the plane needs to drop the supplies BEFORE it reaches the location. How far out (in meters) should the supplies be dropped? (in other words, how far horiszontally will the package go as it falls?) Ignore air resistance.
A rock is thrown horizontally with a speed of 20 m/ s from a vertical cliff of height 25 m. (a) Draw a sketch showing initial velocity of rock and vertical and horizontal displacement. (b) What are x and y components of initial velocity? (c) What are x and y components of acceleration? (d) How long does it take the rock to reach the horizontal ground below? (e) How far will it land from the base of the cliff?
Juliet is standing in front of a wall and Romeo is at a window above her at a height of 3.61 m from the ground. Juliet tosses a box of candy straight up with speed 7.50 m/s from a height of 1.53 m above the ground. Ignore any effects due to air resistance. To receive full marks, you must include a diagram showing the physical situation and your choice of coordinate system. (a) Will the box reach Romeo? O Yes O No (b) If so, what is the box's speed when it reaches Romeo? If not, what initial speed must the rock have to reach Romeo? m/s
An elevator without a ceiling is ascending with a constant speed of 10 m/s. a boy on the elevator throws a ball directly upward, from a height of 2.0 m above the elevator floor, just as a elevator floor is 28 m above the ground. The initial speed of the ball with respect to the elevator is 20 m/s. How long (in seconds) does the ball take to return to the elevator floor? Give the Given and Solution:
A helicopter is ascending vertically with a speed of 3.2 m/s. At a height of 97.1 m above the ground, a package is dropped from the window. How much time does it take for the package to reach the ground? Answer: Check
