The maximum height that is reached by an object thrown or jumped at a certain initial velocity can be calculated through the equation,
2ad = Vf² - Vi²
Vf is zero (0) in this equation because this is the point at the velocity at the maximum height of the object.
Substituting the known values,
2(a)(-16) = 0 - (3.6)²
The value of a from the equation is 0.405 m/s².
<em>Answer: 0.405 m/s²</em>
The magnitude of acceleration is (change in speed) / (time for the change).
Change in speed = (speed at the end) - (speed at the beginning) =
(16 m/s) - (0) = 16 m/s .
Time for the change = 4 s .
Magnitude of acceleration = (16 m/s) / (4 s) = 4 m/s per sec = 4 m/s² .
Answer:
Use equation for kinetic energy: Ek=mV²/2
m=700 kg
V=10m/s
Ek=700kg*100m²7s²/2
Ek=35000 J=35kJ

Do mark me as brainliest
The object is not accelerating. I think I got this question right
Answer:
Heat
Friction is what causes heat.
