Answer:
P = 30380 W
Explanation:
given,
mass of the skydiver, m = 62 Kg
distance, s = 50 m
time, t = 1 s
we know,
F = m g
inserting all the values
P = 30380 W
hence, Power the skydiver expending on the air is 30380 W
B. The resistance is directly proportional to length and inversely proportional to cross sectional area
Answer:
An object with 0 acceleration is accelerating in a direction that is opposite to a stated positive direction.
Explanation:
Acceleration is not always based on speeding up or slowing down (a constant speed is no acceleration at all), it's also based on direction. If you state that an object is positively accelerating when you throw it upwards, then it's negatively accelerating when it's falling even though it's velocity is increasing.
Acceleration = change in velocity/time
= 40/5
=8m/s^2
