a ball with mass 0.15 kg is thrown upward with initial velocity 20 m/sec from the roof of a building 30 m high
A ball is thrown from the top of a building with an initial velocity of 23.7 m/s straight upward, at an initial height of 52.0 m above the ground. The ball just misses the edge of the roof on its way down, as shown in the figure. (a) Determine the time needed for the ball to reach its maximum height. s (b) Determine the maximum height. m (c) Determine the time needed for the ball to return to the height...
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 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...
igh. Neglect air resistance. (A computer algebra system A bal with mass 0.11 kg is thrown upward with iniial velocity 10 m's rom the roof o a building 40 m h to one decimal place.) is recommended. Use g9.8m/s for the acceleration due to gravity. Round your enswers (a) Find the maximum height above the ground that the ball reaches (b) Assuming that the ball misses the building on the way down, tind the time that it hits the ground.

Determine the time of flight when it returns to its initial position. c. Determine the time of flight when it hits the ground. d. Determine the velocity just before it hits the ground. Check your answer using a different equation. e. Plot v(t) and s(t) from...
A ball is thrown vertically upward with a velocity of 15 m/s from the roof of building that is 22 m high. How long does it take to hit the ground below? How fast was it going when it hit?
A baseball is thrown from the roof of 20.6 m -tall building with an initial velocity of magnitude 12.4 m/s and directed at an angle of 55.6 ∘ above the horizontal. a) What is the speed of the ball just before it strikes the ground? Use energy methods and ignore air resistance. b) What is the answer for part (A) if the initial velocity is at an angle of 55.6 ∘ below the horizontal? c) If the effects of air...
A stone thrown from the top of a building is given an initial velocity of 40.0 m/s straight upward. The stone is launched 60.0 m above the ground, and the stone just misses the edge of the roof on its way down. a. Find the maximum height of the stone. b. Using t=0 as the time the stone leaves the thrower’s hand, determine the time at which the stone reaches its maximum height c. Find the velocity and position of...
A baseball is thrown from the roof of a 30.0-m-tall building with an initial velocity of magnitude 17.0 m/s and directed at an angle of 53.1° above the horizontal. (a) What is the speed of the ball just before it strikes the ground? Use energy methods and ignore air resistance. m/s (b) What is the answer for part (a) if the initial velocity is at an angle 53.1° below the horizontal? m/s
A stone thrown from the top of a building is given an initial velocity straight upward, v0,y= 29ms. The height of the building is 50m. Calculate the maximum height, above the ground, the stone reaches. A stone thrown from the top of a building is given an initial velocity straight upward, v0,y= 29ms. The height of the building is 50m. After how long does the stone reach its maximum height ?
