Answer:
Explanation:
The pingpong ball reaches the ground directly under the student. That means net displacement is zero
Time of fall t = 
Initial horizontal velocity = v ,
horizontal acceleration = - a ( deceleration because net displacement is zero)
0 = ut - 1/2 a t²
0 = 
v = 1/2 a 
h = 
911 k divided by 45 k equals the amount that you need to times 24L by.
The answer is ≈ 485.86L
240 = 0+1/2 (-9.8t
240 = -4.9t
<span>240/-4.9 = t</span><span>
</span>49.0 = t
t= 7.0s
Answer:
true

Have a great day/night! ^_^
There will not be enough momentum from the first hill to cross another hill if he same or larger size because of the way potential energy and kinetic energy works it will not be able go as high as it could go on he fist hill.
