Answer :
Answer:
Explanation:
P =F x d / t
P = (mg) x d / t
p= ( 99 x 9.81 ) x 60 / 8.55
p= 6815.4 W
Check:
P= FV
F= mg
P = ( 99 x 9.81 ) x (60 /8.55)
p= 6815.4 W
Final answer:
To find the horizontal power of a sprinter, use the formula w = F · d / t, where F is force, d is distance, and t is time. By substituting the given values and performing the calculation, the horizontal power can be determined to be 87.719 watts.
Explanation:
Horizontal power (w) can be calculated using the formula: w = F · d / t.
Given the force applied by the sprinter, the distance covered, and the time taken, we can substitute these values to find the horizontal power.
- Identify the given values: Force (F) = 30.0 N, Distance (d) = 25.0 m, Time taken (t) = 8.55 s.
- Substitute the values into the formula: w = 30.0 N · 25.0 m / 8.55 s.
- Calculate the horizontal power (w) by performing the multiplication: w = 87.719 watts.
