1) A human cannonball is launched straight up from the top of 100- meter-high rampart at 400 m/s. How long is the cannoneer in the air above the rampart? Answer: 81.6 s

2) A cheerleader is thrown straight up from the ground with an initial velocity of 1.5 m/s. On the way down, she makes eye contact with a fan when she is 2.8m above the field. How much time passes between the initial throw and when they make eye contact? Answer: 1.05 s

3) You throw a basketball from the ground straight up in the air with an initial velocity of 12.2 m/s. On its way down, it passes through a hoop 3.05 m above the ground. How long does it take the ball to reach the ground after it passes through the hoop? Answer: 0.28 s

I included the answers but I don't know how to get it!

Expert Solution

she makes eye contact with a fan when she is 2.8m above the field. This is absurd as maximum height is too less than this, The question in my view has an error.

A projectile is launched straight up at 55.5 m/s from a height of 71 m, at the edge of a sheer cliff. The projectile falls just missing the cliff and hitting the ground below. (a) Find the maximum height of the projectile above the point of firing. m (b) Find the time it takes to hit the ground at the base of the cliff. s (c) Find its velocity at impact. m/s

Part I A ball is thrown straight up from the top of a building that is...

Part I A ball is thrown straight up from the top of a building that is 185ft high with an initial velocity of 64ft/s. The height of the object can be modeled by the equation s(t) = -16t 2 + 64t + 185. In two or more complete sentences explain how to determine the time(s) the ball is higher than the building in interval notation. Part II In two or more complete sentences, describe the transformation(s) that take place on...

A cannonball is fired horizontally from the top of a cliff. The cannon is at height H = 100m above ground level, and the ball is fired with initial horizontal speed v0=0. Assume acceleration due to gravity to be g = 9.80 m/s2. a)Assume that the cannon is fired at time t=0 and that the cannonball hits the ground at time tg. What is the y position of the cannonball at the time tg/2? b) Given that the projectile lands...

A rocket is launched straight up. It contains two stages (Stage 1 and Stage 2) of solid rocket fuel that are designed to burn for 10.0 and 5.0 s, respectively, with no time interval between them. In Stage 1, the rocket fuel provides a net upward acceleration of 18 m/s2. In Stage 2, the net upward acceleration is 13 m/s2. Neglecting air resistance, calculate the maximum altitude above the surface of Earth of the payload and the time required for...
