1. The 10-lb block has a speed of 4 ft/s when the force of F = (8t?) Ib is applied. Determine the
velocity of the block when it moves s = 20 ft. The coefficient of kinetic friction at the surface is
Uz = 0.15. Note: It's okay to use an online equation solver to calculate a number in this
problem!
v = 4 ft/s
F = (8f) lb

loaded 305 kgkg toboggan is traveling on smooth horizontal snow at 4.60 m/sm/s when it suddenly comes to a rough region. The region is 7.90 mm long and reduces the toboggan's speed by 1.50 m/sm/s. Part A: What average friction force did the rough region exert on the toboggan? Part B: By what percent did the rough region reduce the toboggan's kinetic energy? Part C: By what percent did the rough region reduce the toboggan's speed?
10. A stationary block is released on a frictionless ramp at a height of 3.0 m. There are other hill heights along the ramp as shown in the figure. The hills have identical circular tops, and the block does not fly off any hill. If the mass of the block is 4 Kg, what would be the velocity as it passes hill (1)?
