M = 1250 kg
V = 14.0 m/s
t = 7.25 s
F = ?
Impulse equation
F . t = m . V
:. F = mv/t
F = (1250 kg x 14.0 m/s) / 7.25s
F = 2414 N
Answer:
B.
Explanation:
Given that a student runs up a flight of stairs which info is not needed to calculate the rate of the student is doing work against gravity A the height of the flight of stairs B the length of flight of stairs C the time taken to run up the stairs D the weight of the student
The rate of doing work is known as power.
Power = work done/time
Work done = energy = mgh
Since energy = mgh
Where mg = weight
And h = height
Time = time taken to run up the stairs.
Time, weight mg and height h will be needed while the Length of the flight is therefore not needed.
The correct answer is B.
