At t = 0, a variable force given as F = (3t² +15) lbf starts to act on the 10 lbf block as shown. At t = 0, v = 20 ft/s to the right. The coefficient of friction between the block and the plane is 0.3. Determine the velocity after 3 seconds. 30° 10 lb At t = 0, a variable force given as F = (3t² +15) lbf starts to act on the 10 lbf block as shown. At t = 0, v = 20 ft/s to the right.

Answer rating: 100% (QA)

SOLUTION To determine the velocity of the block after 3 seconds we need to consider the forces acting on the block and solve for the resulting acceleration Given Force applied F 3t2 15 lbf Initial vel... View the full answer
