Homework Answers
Sol::
Given
Height(h) = 2.7 m
The time off the ground is double the time it would take to drop
1.65m., as the time is identical from ground to maximum height, and
from maximum height back to ground.
So
t = √(2h/g)
=√(2*2.7/9.8)
= 0.742 s
Doubling it, we get t=1.484 secs.
So Ans:
T= 1.48 s
Hope this helps and will get RATED

A 65 kg kangaroo jumps vertically to a height of 1.8 m. Assume that there is very little horizontal motion, and that air resistance is negligible. a) What is its potential energy at the top of its jump? b) What must its kinetic energy have been at the beginning of the jump, the moment after its feet left contact with the ground? c) Based on your answer from (b), what was the kangaroo's initial upward velocity, just after leaving the...

When you throw a ball straight up, it slows down until it comes to a stop at its greatest height and then accelerates downward. The time it takes for a ball thrown upward to reach a height, , is given by . The initial velocity needed to get it to that height is given by How long will a ball be in the air on Earth that you throw to a height of 6.525 m?

Determine how long it will take until the rocket reaches
macimum height
A small rocket of weight 1.2 lbs is launched vertically with thrust 7 lbs from a stand on the ground at timet -0 seconds. It has a constant thrust for the first second, then no thrust after that. We will assume no air friction and ignore the mass change of the rocket for now. Determine how long it will take until the rocket reaches maximum height

A rocket rises vertically, from rest, with an acceleration of 4.0 m/s2 until it runs out of fuel at an altitude of 1500 m . After this point, its acceleration is that of gravity, downward. With what velocity does the rocket strike the Earth? How long (total) is it in the air?

A 82 kg person has his center of gravity 1.0 meters above the ground in a standing position (height that person comes off the ground during a jump). During a squat jump, he crouches down so that his centre of gravity is 0.3 meters above the ground. As he jumps, he exerts an average force of 1258 Newtons against the ground. You can think of this average exerted force as the average normal force or average ground reaction force being...
