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 .
