Question
A car has a mass of 1700 kg, a drag coefficient of 0.35, a rolling resistance coefficient of 0.01, a frontal area of 2 m2, and a horsepower of 150. What is the minimum time required for the car to go from 0 to 60 mph? What is the minimum time if the car has 300 horsepower, with all else the same? Use a density of air of 1.2 kg/m3, and g = 9.8 m/s2. Assume the car is on a perfectly flat surface and assume that the wheels don't slip.

- Power of the Human Heart. The human heart is a powerful and extremely reliable pump. Each day it takes in and discharges about 7500 L of blood. Assume that the work done by the heart is equal to the work required to lift this amount of blood a height equal to 1.5 m. The density (mass per unit volume) of blood is 1050 kg/m3 .

- 2. Tarzan, whose weight is W = 688 N, swings from a vine of length L = 18 m. He starts his swing from rest at the edge of a cliff that is h = 3.2 m above the bottom of his trajectory. The vine will break if its tension exceeds T 900 N. W (a) Does the vine break? If the vine does not break, what is the greatest (b) tension in the vine? If the vine breaks, at what angle with respect to the vertical will it break?arrow_forwardA toy gun fires a 9.41 g projectile disc by using a compressed spring (k= 1720 N/m). The barrel of the gun is 13.1cm (this is measured after the spring). As soon as the projectile goes leaves the spring, it creates thermal energy due to friction. The frictional force is 0.130N. If you compress the spring 14.0mm, what is the speed of the projectile when it leaves the gun?arrow_forwardExplain this formulaarrow_forward
