The distance travelled by the bike can be calculated by using the basic relationship between speed (v), distance (S) and time (t):

Rearranging the equation, we get

The speed of the bike is v=3 m/s, the time is t=30 s, so the distance travelled by the bike is

Given :
A 13.3 kg box sliding across the ground decelerates at 2.42 m/s².
To Find :
The coefficient of kinetic friction.
Solution :
Frictional force applied to the box is :
....1)
Also, force of friction is given by :
....2)
Equating equation 1) and 2), we get :

Therefore, the coefficient of kinetic friction is 0.247 .
We can only corelate the object's weight with the amount of water it was able to displaced.
If the water displaced was around 400N, then the amount of liter displaced is around 400 N (kg*m/s²) / 9.8 m/s² (earth's gravitational pull) which is equals to ~40.81 liters which should be the objects mass as the best assumption (1kg = 1L). As there is no direct link between the water displaced and actual object weight.
