Answer:
Check Explanation.
Step-by-step explanation:
s(t) = 0.810t²
a) Distance fallen through, just after t = 8 s
s(8) = 0.810(8²) = 51.84 m
b) Velocity of the body, just after t = 8 s
s(t) = 0.810t²
v(t) = (ds/dt) = 1.620t
v(8) = 1.62(8) = 12.96 m/s
c) Acceleration of the body, just after t = 8 s
v(t) = 1.620t
a(t) = (dv/dt) = 1.620
a(8) = 1.620 m/s²
d) The answer obtained from the 2nd derivative of this free fall function for acceleration is a constant.
This means, the acceleration of the body is constant regardless of the time.
The body undergoing the motion described by the free fall function has a constant acceleration.
45 | 45 divided by 5 = 9
So i think if we do the same for 70 we will get the length
70| 70 divided by 5 = 14
So the length = 14
