Question

You and your friend Peter are putting new shingles on a roof pitched at 21°. You're sitting on the very top of the roof when Peter, who is on the edge of the roof, 5.4 m away, asks you for the box of nails. Rather than carry the 2.5 kg box of nails down to Peter, you decide to give the box a push and have it slide down to him. If the coefficient of kinetic friction between the box and the roof is 0.55, with what speed should you push the box to have it gently come to rest right at the edge of the roof? Express your answer with the appropriate units. ? View Available Hint(s) $v = $ Value Units Submit

Step 1

The force of gravity acting on the box is given by Fg = m * g, where m = 2.5 kg is the mass of the box and g = 9.8 m/s^2 is the acceleration due to gravity. Fg = 2.5 kg * 9.8 m/s^2 = 24.5 N The component of the force of gravity parallel to the roof is Fpar = Fg * Show more…
