Answer:speed of slower cyclist is 5 mph
Explanation:
Given
Distance between two cyclist is 50 miles
One cycle is 4 times fast as other
Speed of slower cyclist is r miles per hour
speed of faster cyclist is 4 r
they meet after t=2 hr
Distance traveled by fast cyclist is 
Distance traveled by slower cyclist is 






speed of slower cyclist is 5 miles per hour
Watt is a unit for power that is also equal to J/s. We therefore need to convert the minutes to seconds first before answering. Every minute is comprised of 60 seconds. Therefore, 3 minutes are composed of 180 seconds. Multiplying the number of seconds to the given power will give us,
Work = Power x time
= (1500 J/s) x (180 s)
= 270,000 J
Therefore, the answer is letter D.
We have:
Total Energy: KE + GPE
KE (Kinetic Energy) =

GPE (Gravitational Potential Energy) =

Data:
m (mass) = 2.0 Kg
v (speed) = 10 m/s
h (height) = 50 m
Use: g (gravity) = 10 m/s²
Formula:
Total Energy: KE + GPE

Solving:
