carton is given a push across a horizontal surface. The carton has a mass m, the push gives it an initial speed of 1.70 m/s, and the coefficient of kinetic friction between the carton and the surface is 0.150. (a) Use energy considerations to find the distance (in m) the carton moves before it stops. (No Response) m (b) What If? Determine the stopping distance (in m) for the carton if its initial speed is doubled to 3.40 m/s. (No Response) m
A carton is given a push across a horizontal surface. The carton has a mass m, the push gives it an initial speed of 1.70 m/s, and the coefficient of kinetic friction between the carton and the surface is 0.150.
Kinetic friction opposes the motion and hence deaccelerate the carton.
......(1)
due to the push the carton starts moving but as the frictional force comes into effect it stops the carton after certain distance. third equation of motion is
......(2)
where v is the final velocity
u is the initial velocity
a is the acceleration, in this case this is retardation due to kinetic friction
s is the stopping distance
