a) A man jumps off the roof of an office building onto a trampoline 30 m below. His speed is 5 m/s when he umps from the roof and his mass (with all of her gear) is 60 kg. How high will he go when he bounces back up from the trampoline? You can assume his speed at the top of his bounce is zero. b) Describe the changes in mechanical energy that take place during his jump. c) A...
1) You (a person with mass m) have a trampoline that you would like to treat like a spring. You decide to jump from a height h above the flat surface of the trampoline, and you measure that you travel a distance h/4 downward after hitting the surface of the trampoline. In terms of known variables, determine the effective spring constant and the speed at which you hit the trampoline. I need the velocity.
A bike rider takes off from a jump and travels 4 meters horizontally through the air in 2.75 seconds. Assuming she takes off and lands at the same height, How high did she go during the jump? (2 pt) What was her resultant take-off velocity (2pt-magnitude and 2pt-direction)?
a person throws a ball upward into the air with an initial velocity of 15 m/s calculate a)how high it goes? b)how long the ball is in the air before it comes back ? c)how much time it takes for the ball to reach the maximum height?
an object have been thrown vertically into the air with an initial velocity of 6 m/sec. a) how high will the object go? b) how much time will the object remain in the air before it comes back to the same place? An object has been thrown vertically into the air with an initial velocity of omso A) How high will the object go? B) How much time will the object remain in the air before it comes back to...
If a ball is thrown straight up at 20 m/sec and takes 4.08 seconds to return to your hand, how high did the ball go?
Janet jumps off a high diving platform with a horizontal velocity of 2.07 m/s and lands in the water 1.9 s later. How high is the platform? The acceleration of gravity is 9.8 m/s^2. Answer in units of m. How far from the base of the platform does she land? Answer in units of m.
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 person bounces up and down on a trampoline, while always staying in contact with it. The motion is simple harmonic motion, and it takes 2.73 s to complete one cycle. The height of each bounce above the equilibrium position is 45.2 cm. Determine (a) the amplitude and (b) the angular frequency of the motion. (c) What is the maximum speed attained by the person?
A BMX cyclist rides off a 2.50m high ramp with an initial velocity of 18.0 m/s at an angle of 40.0 degrees above horizontal. Find the time it takes for the cyclist to land on the gound and the distance from the base of the ramp to the landing point.
