A parachutist jumps out of an airplane and accelerates with gravity to a maximum velocity of 58.8 m/s in 6 seconds. She then pulls the parachute cord and after a 4 second deceleration, descends at 10 m/s for 60 seconds. reaching the ground. From what height did the parachutist jump?
A person standing at the edge of a cliff throws a rock upward from a height of 350ft above ground level with an initial velocity of 65⁢ft/s. What is the velocity of impact when the rock reaches the bottom of the cliff? Round any intermediate calculations, if needed, to no less than six decimal places, and round your final answer to two decimal places. (Hint: Use h(t)=−16t2+65t+350 as the position function, where hh is in feet, tt in seconds. Ignore air resistance.)
A student holds a ball 1.55 meters above the ground and drops it. Her friend uses a stopwatch and measures a time of 0.57 seconds for the ball to hit the ground. The ball accelerates due to gravity. Using the equation y = 1/2??2 where y is the height, to compute g , calculate the acceleration of the ball.
A ball is thrown downward with a speed of 8 ft/s from the top of a 64-foot-tall building. After t seconds, its height above the ground is given by s(t)=−16t^2−8t+64. a. Determine how long it takes for the ball to hit the ground. b. Determine the velocity of the ball when it hits the ground.
An object is thrown from a level field with initial upward speed 17 m/s and forward speed 9.9 m/s. How far (in m) from its launch point is its landing place? You do not need to put the unit in the answer, just the number. As usual, ignore air resistance, etc; use the acceleration due to gravity as 9.8 meters per second squared.
The height of an object thrown upward with an initial velocity of 96 feet per second is given by the formula h = −16t2 + 96t, where t is the time in seconds. a) How long will it take the object to reach a height of 144 feet? b) How long will it take the object to return to the point of departure?
A small bag of sand is released from an ascending hot‑air balloon whose constant, upward velocity is ?0=2.15 m/sv0=2.15 m/s. Knowing that at the time of the release the balloon was 58.8 m58.8 m above the ground, determine the time ?τ it takes for the bag to reach the ground from the moment of its release. Use ?=9.81 m/s2.
Sabrino is walking down a road when he observes a nearby mountain that a boulder is falling, he notices that it took 1.30 seconds for the boulder to fall the last third of its way to the ground. So, in that situation, what is the height of the mountain?
A well-thrown ball is caught in a well-padded mitt. If the deceleration of the ball is 2.10×104 m/s2 , and 1.85 ms (1 ms = 10-3 s) elapses from the time the ball first touches the mitt until it stops, what was the initial velocity of the ball?
The height of a helicopter above the ground is given by y(t)=4.5t^(2), in meters. After 2.0 seconds the helicopter releases a mailbag, how long does it take for the mailbag to hit the ground?
A classic physics problem states that if a projectile is shot vertically up into the air with an initial velocity of 146 feet per second from an initial height of 89 feet off the ground, then the height of the projectile, hh, in feet, tt seconds after it's shot is given by the equation: h=−16t2+146t+89h=-16t2+146t+89 Find the two points in time when the object is 126 feet above the ground (to one decimal places). Answer: The object is 126 feet off the ground at the following times: (Enter your two answers separated by a comma. Round to ONE decimal places.)
The height (in meters) of a projectile shot vertically upward from a point 4 m above ground level with an initial velocity of 25.5 m/s is h = 4 + 25.5t − 4.9t2 after t seconds. When does it hit the ground and at what velocity does it hit the ground
