A 3.4-kg box is released on a horizontal surface with an initial speed of 4.8 m/s. It moves on the surface with a deceleration of 0.45 m/s2. Calculate the kinetic friction force on the box.
F = m a
To calculate the kinetic friction force on the box, we can use the equation:
Friction force = mass x deceleration
Given:
Mass of the box (m) = 3.4 kg
Deceleration (a) = 0.45 m/s^2
Using the equation, substitute the values:
Friction force = 3.4 kg x 0.45 m/s^2
Now, calculate the friction force:
Friction force = 1.53 N
Therefore, the kinetic friction force acting on the box is 1.53 N.
