1. A rock is dropped from a bridge that is 15 m above the surface of the river. How long does it take for the rock to hit the water? 2. A ball is thrown upward from the edge of the roof of a 20 m tall building with an initial velocity of 15 m/s. a) What is the maximum height reached by the ball? b) How much time does it take for the ball to reach the ground? c)...
A rock is thrown vertically upward with a speed of 15.0 m/s from the roof of a building that is 70.0 m above the ground. Assume free fall. In how many seconds after being thrown does the rock strike the ground? What is the speed of the rock just before it strikes the ground?
A ball A is thrown vertically upward from the top of a 33-m-high building with an initial velocity of 3 m/s. At the same instant another ball B is thrown upward from the ground with an initial velocity of 23 m/s. Determine the height from the ground at which they pass. Determine the time at which they pass.
A rock is thrown vertically upward with a speed of 11.0 m/s from the roof of a building that is 60.0 mabove the ground. Assume free fall. 1) In how many seconds after being thrown does the rock strike the ground? 2)What is the speed of the rock just before it strikes the ground?
A basketball is thrown vertically upward with an initial velocity of 22.8 m/s. 'a) How long (s) does the ball take to reach its maximum height? 'b) How high (km) does the basketball go?
A ball is thrown vertically upwards with an initial velocity of 18.80 m/s, from the ground. How long is the ball in the air? (Neglect air resistance.) What is the greatest height reached by the ball? Calculate the time at which the ascending ball reaches a height of 12.8 m above the ground. A rocket, initially at rest on the ground, accelerates straight upward with a constant acceleration of 53.0 m/s^2, until the fuel is used up after 6.80s. What...

(c) How long does the ball take to hit the ground after it reaches its highest point? (d) What is its velocity when it returns to the level from which it started? 2. It is possible to shoot an arrow at a speed as high as 100 m/s. (a) If...
At t = 0 s, a ball B1 is thrown vertically upward with a speed of 30 m/s. When B1 is 25 m above ground on the way up, a second ball B2 is thrown vertically upward from the ground with a speed of 40 m/s (Take the magnitude of the acceleration due to gravity g =10m/s2) a) How many seconds after B1 was B2 thrown upward?
A ball is thrown vertically upwards with a velocity of 29.5 m/s, from a window 84 m high. How long before the ball hits the ground?
