Answer:
The answer would be 735J
Explanation:
PE=mgh
=(mass)(force of gravity)(height)
=(25kg)(9.8m/s^2)(3m)
=735J

The fastest time trial for the first quarter checkpoint is 2.02 s.
The slowest time trial for the first quarter checkpoint is 2.7 s.
The range of the times measured for the checkpoint is 0.68 s.
The given parameters;
- <em>Time for quarter checkpoint, = 2.15, 2.05, 2.02, 2.7</em>
The fastest time trial for the first quarter checkpoint is the least measured time value.
<em>fastest time trial = least time measured</em>
fastest time trial = 2.02 s
The slowest time trial for the first quarter checkpoint is the highest measured time value.
slowest time trial = 2.7 s
The range of the times measured for the checkpoint is difference between the fastest time and slowest time.
<em>Range = fastest time - slowest time</em>
Range = 2.7 - 2.02
Range = 0.68 s

Answer: a = 0.647 m/s^2
Explanation:
Acceleration = change in speed / time → a = 22 / 34 → a = .647 m/s^2
