It would take the bicyclist 9 seconds to move 36m.
Answer: 
Explanation:
In this case we are talking about the centripetal acceleration 
, which can be calculated by:
Where:
is the speed of the motorcycle
is the radius of the path the motorcycle is going around
Solving:
Finally:
The distance between Los Angeles and San Francisco is approximately 381.9mi.
Divide this distance by the speed.
381.9/72 = 5.3
You are left with the time in hours. To convert to minutes, multiply by 60.
5.3*60 = 318.25
Therefore, it will take 318.25 minutes.
Answer:
2280 V
Explanation:
distance between the plates, d = 4 cm = 0.04 m
Electric field strength, E = 5.7 x 10^4 V/m
The formula for potential difference is given by
V = E x d
V = 5.7 x 10^4 x 0.04
V = 2280 V
thus, the potential difference between the plates is 2280 V.
you need to use hours to make it easy to convert to m/s. Change 15 minutes to hours
Note distance is in km so change the time to hours to get km/hour
1 hour = 60mins so 15 minutes will be 0.25 hours
10/0.25 = 40 km/ hour
To change that to m/second, change km to meters and hour to second
it will be (40x1000) meters /3600seconds
11.1111 m/s
