Answer:
A, I think its A but im not sure.
Explanation:
Answer:
1 mile
Explanation:
The distance travelled is the length of the path that the runner traveled.
As you have stated he has traveled a 1 mile track so the length he traveled is 1 mile.
The point of ending matters only in displacement not in distance. In displacement we measure the unidirectional shortest distance between two points where the displacement in this case is 0.
Answer:
Because you need to have that momentum to decease over a little bit of time because if it doesn't have room to move backward, that force isn't going to reduce and it will hurt very badly.
Power in watts is 2400 W and in horse power is 3.218 hp.
Explanation:
Power is defined as the amount of work done per unit time. From work energy theorem, the work done is equal to the difference in the kinetic energy. Since the initial speed is zero, so the initial kinetic energy will be zero. So the work done is equal to the final kinetic energy.
As the mass is 50 kg and velocity is 14.2 m/s with time 2.1 s, then the work done will be
Then this need to be convert to horse power as 1 horse power = 745.7 W.
So, power in horse power will be
So power in watts is 2400 W and in horse power is 3.218 hp.
