A kangaroo will stay 0.699s in the air when he jumps.
<h3>What motion does the projectile make?</h3>
A projectile is an object that is launched vertically into the air and moves while being pulled by gravity. A projectile is an object that is launched into the air horizontally and moves regardless of gravity.
<h3>How do you determine the rate of descent?</h3>
G = -9.81 m/s2 is the acceleration of gravity close to the earth. Simply multiply the acceleration of gravity by the period since the object was released to determine the object's speed (or velocity). In other words, velocity is equal to -9.81 m/s2 * time, or V = gt.
<h3>According to the given information:</h3>
From the conversion of energy =
t = √(2h/g)
= √((2 x 2.40) / 9.8)
=0.699 s
A kangaroo will stay 0.699s in the air when he jumps.

The answer is C) C and E.
The wavelength, or the period of the wave, is the length or amount of time of one complete cycle, meaning the time it takes for the wave to return to its original position. A period involves one trough, one crest, and a return to rest, or the zero. We can see that this occurs between C and E.
Another way to look at it is the period of time, or length, before the wave returns to its original position. Where the measurement starts isn't really relevant, as long as the measurement is where the wave returns to that position.
Something must be wrong in the data you have, since this is basic using of linear motion's formulas.
vf=v0+at. Where vf= final velocity; v0= initial velocity, a=acceleration and t=time.
If the rocket is initially at rest, v0=0. Therefore vf=at. Plugging numbers in gives 445=99*4.5, However
445≠445.5.
Check it and then calculate the distance from x=a*t^2.
