To determine the acceleration of the object, we can use the equation a = (final velocity - initial velocity) / time. In this case, the final velocity is 40 m/s, the initial velocity is 0 m/s, and the time is 18.34 seconds. Plugging these values into the equation, we get:
a = (40 - 0) / 18.34
a ≈ 2.18 m/s^2
To compute the force of kinetic friction, we can use the equation Friction Force = mass * acceleration. However, the given information does not include the mass of the object. Therefore, we cannot calculate the force of kinetic friction.
To determine the coefficient of kinetic friction, we need the value of the normal force (N). The equation for kinetic friction is given by Friction Force = coefficient of kinetic friction * N. Since the normal force is not provided, we cannot calculate the coefficient of kinetic friction.
In summary:
1. The acceleration of the object is approximately 2.18 m/s^2.
2. The force of kinetic friction cannot be calculated without the mass of the object.
3. The coefficient of kinetic friction cannot be determined without the value of the normal force.
