Spider-Man launches himself from the ground so that he travels vertically upward, eventually catching hold of a hovering helicopter that is 420 m above the ground. Assume air resistance is negligible as he ascends . ( g = 9 . 8m/s 2 ) What minimum initial takeoff speed must Spider-Man have to reach the helicopter?

A painter is standing on scaffolding that is raised at constant speed. As he travels upward, he accidentally nudges a paint can off the scaffolding and it falls a distance 15.1 m to the ground. You are watching, and measure with your stopwatch that it takes a time of 3.30 s for the can to reach the ground. Ignore air resistance. What is the speed of the can just before it hits the ground? m/s Submit Request Answer

When it is 159 m above the ground, a rocket traveling vertically upward at a constant 8.30 m/s relative to the ground launches a secondary rocket at a speed of 12.4 m/s at an angle of 53.0 ∘ above the horizontal, both quantities being measured by an observer sitting in the rocket. Air resistance should be ignored. Part A : Just as the secondary rocket is launched, what are the horizontal and vertical components of its velocity relative to the...

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...
