A box of weight 74 N is sliding on a horizontal surface at a constant velocity due to an external force F of magnitude 4.8 N. A normal force (n) and a friction force (f) also act on the box. What is the magnitude of the friction force?

3. A block of ice is sliding down a ramp with a constant acceleration of 4.9 m/s2. What is the angle between the slope of the ramp and the horizontal? Assume the force of friction is not significant.
