Explanation:
The acceleration of a car moving with speed v in a circle of radius R is given by:
Now if we double the speed in the equation above, it becomes . Thus:
Therefore the acceleration is increased by a factor of 4.
Answer:
Distance covered by Joe, d = 5 km
Explanation:
It is given that,
Speed of Joe, v = 20 km/hour
Time taken by Joe, t = 15 minutes = 0.25 h
We need to find the distance he is covering. It can be calculated using definition of speed as :
d = 5 km
So, Joe covers a distance of 5 km. Hence, this is the required solution.
