First of all we can dig a hole as told only if earth is entirely solid. So let's assume earth as a solid ball with a hole from one side to other.

Now just jump through the hole. At beginning of jump the speed is zero but you will fall because of gravitational force. (Like freely falling body)
At point ‘A' your speed increases due to gravity and acceleration due to gravity decreases gradually(I.e. force on you).
When you reach centre 'B' there will be no force acting on you(I.e. acceleration is ‘0’) however you have momentum(you will reach maximum velocity) therefore you will continue through the hole.
Then you reach point 'C', here your velocity is less compared to velocity at cente because of deceleration.
When you reach point 'D'(other end of hole) your momentum reaches zero(velocity becomes zero because force is acting on you downwards) & acceleration due to gravity has again increased. So now again you fall through the hole.
As long as there is no energy loss you will continue to oscillate to and fro. This motion is called simple harmonic motion.
It takes you around 42 minutes 12 seconds to reach other side. However this all happens by neglecting earth's rotation. If you consider even earth's rotation then the results will be different(you will die).
