Chapter 1: Q16DQ (page 159)

A curve in a road has a bank angle calculated and posted for 80km/h. However, the road is covered with ice, so you cautiously plan to drive slower than this limit. What might happen to your car? Why?

Short Answer

Expert verified

The car may slip from the road as the frictional force is less, so it is driven slowly.

Step by step solution

01

Significance of the banking angle

The banking angle is the angle at which the road鈥檚 outer edges are being raised. The banking angle helps the vehicles to move on the horizontal road that is curved.

02

Explanation of the things that might happen to the car

As the road is covered with ice, the frictional force between the road and the tire is significantly reduced as compared to the one in absence of ice. Hence, if the speed of the car increases, the car may slip from the road.

Thus, the car is driven slowly on ice.

Question:The density of gold is 19.3 g/cm3 . What is this value in kilograms per cubic meter?

In March 2006, two small satellites were discovered orbiting Pluto, one at a distance of 48,000 km and the other at 64,000 km. Pluto already was known to have a large satellite Charon, orbiting at 19,600 km with an orbital period of 6.39 days. Assuming that the satellites do not affect each other, find the orbital periods of the two small satellites withoutusing the mass of Pluto.

A car and a truck start from rest at the same instant, with the car initially at some distance behind the truck. The truck has a constant acceleration of20m/s2, and the car has an acceleration of3.40m/s2. The car overtakes the truck after the truck has moved60.0m. (a) How much time does it take the car to overtake the truck? (b) How far was the car behind the truck initially? (c) What is the speed of each when they are abreast? (d) On a single graph, sketch the position of each vehicle as a function of time. Takex=0at the initial location of the truck.

Question: The purity of gold can be tested by weighing it in air and in water. How? Do you think you could get away with making a fake gold brick by gold-plating some cheaper material?

A rather ordinary middle-aged man is in the hospitalfor a routine checkup. The nurse writes 鈥�200鈥� on the patient鈥檚medical chart but forgets to include the units. Which of these quantities could the 200 plausibly represent? The patient鈥檚 (a) mass in kilograms; (b) height in meters; (c) height in centimeters;(d) height in millimeters; (e) age in months
