Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.
3277.8 because wave speed is calculated by the equation Speed= wavelength • frequently
Answer:
Manuel function can be used when we move it. Oscillate function automatically moves on its own. The pulse function mimics the pulse of a heart rate and can only be used by pushing the button.
Explanation:
Answer:
2.5 seconds
Explanation:
s(t) = -16t^2 + 80t + 384
for
0≤t≤8
First we differentiate s(t) to get s'(t)
s'(t) = -32t + 80
Let us then find the critical point; thus we will equate s'(t) to zero and then search for values where s'(t) is undefined
s'(t) = -32t + 80 = 0
t = 80/32
t = 2.5 sec
Let us evaluate s at the critical points and end points
s(0) = -16(0)^2 + 80(0) + 384 = 384
s(2.5) = -16(2.5)^2 + 80(2.5) + 384 = 684
s(8) = -16(8)^2 + 80(8) + 384 = 0
Thus, the stone attains it maximum height of 684ft at at t=2.5s
It stops cause of gravitaional pull
