Page 5 of 5 Q7 A wagon of mass 20,000 kg is lowered down an incline of 1 in 20 by means of a cable, parallel to the incline, wound around a drum at the top of the slope. The mass of the drum is 550 kg, its radius of gyration is 0.6 m and its effective diameter is 1.5 m. The total resisting (friction) torque at the drum bearings is 2000 N m, and the resistance to motion of the wagon is 2500 N. Determine the braking torque required on the drum to bring the wagon to rest from 25 km hr-1 in 7 m. Neglect the angular inertia of the wagon wheels and the weight of the cable.

The acceleration (a vector quantity) of gravity on a sky diver is 9.8 m/s². If the force of the wind also causes an acceleration of 2.4 m/s² at an angle of 17° above the horizontal, what is the resultant acceleration of the sky diver? Set up the problem by representing each force as a vector. Let S represent the downward force on the sky diver due to gravity, let W represent the upward force on the sky diver due to the wind, and let R represent the resultant vector. Vector Magnitude Standard-position Angle S W

Howie Long has just learned he has won a $500,000 prize in the lottery. The lottery has given him two options for receiving the payments. (1) If Howie takes all the money today, the state and federal governments will deduct taxes at a rate of 46% immediately. (2) Alternatively, the lottery offers Howie a payout of 20 equal payments of $36,000 with the first payment occurring when Howie turns in the winning ticket. Howie will be taxed on each of these payments at a rate 25%. Instructions Assuming Howie can earn an 8% rate of return (compounded annually) on any money invested during this period, which payout option should he choose? NOTE: Enter a formula, a cell reference, or a value (if you are unable to reference a cell), into the yellow shaded input cells.
