Starting from rest, a 4.20-kg block slides 2.40 m down a rough 30.0° incline. The coefficient of kinetic friction between the block and the incline is 𝜇k = 0.436. Determine the work done by the friction force between the block and incline.
Added by Jessica E.
Step 1
The gravitational force can be calculated using the formula: F_gravity = m * g where m is the mass of the block and g is the acceleration due to gravity (9.8 m/s^2). Given: m = 4.20 kg F_gravity = 4.20 kg * 9.8 m/s^2 = 41.16 N Show more…
