The average power produced by the soccer player is 710 Watts.
Given the data in the question;
- Mass of the soccer player;
- Energy used by the soccer player;
- Time;
Power;
Power is simply the amount of energy converted or transferred per unit time. It is expressed as:
We substitute our given values into the equation
Therefore, the average power produced by the soccer player is 710 Watts.

Answer:
3.43 x 10⁵ N/m
Explanation:
M = mass of the car alone = 2000 kg
m = mass of the four people combined = 315 kg
x = compression of the spring when there is car alone
x' = compression of the spring when there is car and four people = x + 0.009
k = spring constant
When there is car, the weight of the car is balanced by the spring force and the force equation is given as
k x = Mg
k x = (2000)(9.8)
k x = 19600 eq-1
When there is car and four people, the weight of the car and four people is balanced by the spring force and the force equation is given as
k x' = (M + m) g
k (x + 0.009) = (2000 + 315) (9.8)
k x + 0.009 k = (2000 + 315) (9.8)
using eq-1
19600 + 0.009 k = 22687
k = 3.43 x 10⁵ N/m
Answer:
18.7842493212 W
Explanation:
T = Tension = 1871 N
= Linear density = 3.9 g/m
y = Amplitude = 3.1 mm
= Angular frequency = 1203 rad/s
Average rate of energy transfer is given by
The average rate at which energy is transported by the wave to the opposite end of the cord is 18.7842493212 W
Answer:
Distance d=8.63m
Explanation:
mass of object m=47.5 kg
Initial velocity vi=0 m/s
Magnitude of force on object F(t)=(17.0 N/s)t
To find
Distance
Solution
The rocket accelerates due to variable force so we apply Newtons second law but the acceleration will not be constant because the force is not constant
We use ax=Fx/m to find acceleration but it must be integrate to find velocity and then the distance that rocket travels
So
Distance d=8.63m
Explanation:
classical physics and modern physics.
