Chapter 7.4, Problem 50E
Movement of a Motorboat Suppose we would like to cross a 132-ft-wide river in a motorboat. Assume that the motor- boat can travel at 7.0 mph relative to the water and that the current is flowing west at the rate of 3.0 mph. The bearing θ is chosen so that the motorboat will land at a point exactly across from the starting point.
(a) At what speed will the motorboat be traveling relative to the banks?
(b) How long will it take for the motorboat to make the crossing?
(c) What is the measure of

The angular velocity of the chainring will determine the linear speed at which the chain travels.

The angular velocity of the sprocket depends upon the linear speed of the chain. The sprocket and rear wheel rotate at the same rate, and the diameter of the rear wheel is 700 millimeters. The speed at which the cyclist travels is determined by the angular velocity of his rear wheel. Use this information to answer Problems 63 through 67.

- Cycling When a cyclist pedals. he turns a gear, called a chainring. The angular velocity of the chainring will determine the linear speed at which the chain travels. The chain connects the chainring to a smaller gear, called a sprocket, winch is attached to the rear wheel (Figure 11). The angular velocity of the sprocket depends upon the linear speed of the chain. The sprocket and rear wheel rotate at the same rate, and the diameter of the rear wheel is 700 millimeters. The speed at which the cyclist travels is determined by the angular velocity of his rear wheel. Use this information to answer Problems 63 through 67. If a cyclist was using her 150-millimeter-diameter chainring and pedaling at a rate of 95 revolutions per minute, what diameter sprocket would she need in order to maintain a speed of 24 kilometers per hour?arrow_forwardCycling When a cyclist pedals. he turns a gear, called a chainring.

A pro cyclist is climbing Mount Ventoux, equipped with a 150-millimeter-diameter chainring and a 95-millimeter-diameter sprocket. If he was pedaling at a rate of 90 revolutions per minute, find his speed in kilometers per hour.

- Length of a Guy Wire A communications tower is located at the top of a steep hill, as shown. The angle of inclination of the hills is 58. A guy wire is to be attached to the top of the tower and to the ground, 100 m downhill from the base of the tower. The angle in the figure is determined to be 12. Find the length of the cable required for the guy wire.arrow_forwardMotion of a Projectile If a projectile (such as a bullet) is fired into the air with an initial velocity v at an angle of elevation (see Figure 10), then the height h of the projectile at time t is given by h=16t2+vtsin Give the equation for the height, if v is 1,500 feet per second and is 30.arrow_forwardHeight You are holding one of the tethers attached to the top of a giant character balloon that is floating approximately 20 feet above ground level. You are standing approximately 100 feet ahead of the balloon (see figure). (a) Find an equation for the length l of the tether you are holding in terms of h, the height of the balloon from top to bottom. (b) Find an equation for the angle of elevation from you to the top of the balloon. (c) The angle of elevation to the top of the balloon is 35. Find the height h of the balloon.arrow_forward
