How long does it take the ball to reach the maximum height? 0.82 s 1.02 s 0.63s 1.22 s What is the maximum height reached by the ball? 5.10 m 3.26 m 7.34 m 1.96 m The vertical component of the acceleration of a projectile remains constant during the entire trajectory of the projectile. True False For a projectile launched horizontally, the horizontal component of...
A ball is thrown straight up. It passes a 2.00-m-high window 7.50 m off the ground on its path up and takes 0.312 s to go past the window. What was the ball's initial velocity? Next, consider only the distance from the ground to the bottom of the window, and solve for the initial velocity using the velocity at the bottom of the window as the final velocity.
A ball is thrown straight up with an initial speed of 14.3 m/s. At what height above its initial position will the ball have one-half its initial speed? height:
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...
