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
Answer:
7200N
Explanation:
Centripetal force is directly proportional to the product of the mass and the square of the velocity and inversely proportional to the radius given.
To find or discover by investigation?
Answer:
Both balls have the same speed.
Explanation:
Janelle throws the two balls from the same height, with the same speed. Both balls will have the same potential and kinetic energy. Energy must be conserved. When the balls pass Michael, again they must have the same potential and kinetic energy.
Answer:
240m/s
Explanation:
The equation to calculate is wavelength= velocity/ frequency so to find the velocity you would have to multiply frequency by wavelength.
