The car's average speed during that time is (23.7/2) = 11.85 m/s .
Distance = (11.85 m/s) x (6.5 sec) = 77.025 meters .
In this problem, you are asked to find a vertical position of a ball when you are given its initial position on a spring. In both locations, the speed of the ball is zero.
If non-conservative forces are either known or small and if energy is converted from one form to another between the locations, then any time you relate speed and position of an object at two different points, conservation of energy is the most direct way to understand the problem.
In this case, you start out with stored energy in the compression of the spring and convert it to stored gravitational energy.
The best and most correct answer among the choices provided by the question is drag<span>.

Mass=density*volume
1*40=40g/0.04kg
Since the biker is moving at constant speed
so we will have
here we know that
time = 4 second
now we have
now at the top point it feels free fall
so it is
so height of the bike at the top is same as diameter
Yes it will hurt on falling from this height
