How much power was used by a cyclist when it took them 2.5 hours to finish their race. The cyclist exerted a force of 32N and the race was 75km long. Must convert km to m prior to calculations. Must show all work, have correct sig figs, and include correct units for full credit.

Explanation:

Given:

Force, f = 32 N

Distance, d = 75 km

1 km = 1,000 m

75 km × 1000 m/1 km

= 75,000 m

Time, t = 2.5 hours

60 secs = 1 min

60 mins = 1 hour

2.5 hours × 60 mins/ 1 hour × 60 sec/1 min

= 9,000 secs

Power = energy/time

Energy = force × distance

Power = (32 × 75,000)/9,000

= 266.67 W

just did the assignment and the answer was #1 +2 n

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
