A river flows toward the east. Because of your knowledge of physics, you head your boat 27 degrees north of west and have a velocity of 7.2 m/s due north relative to the shore. What is the velocity of the current? What is your speed relative to the water? If a small planet were located eight times as far from the sun as the Earth's distance from the sun, how many years would it take the planet to orbit the...

An airplane reaches its takeoff speed of 60 m/s with constant acceleration in 30 s, starting from rest. The time it takes to go from 40 m/s to 60 m / s is: A car starts moving from rest with an acceleration of 0.40 m/ s2. A minute later the acceleration stops, and the car moves with constant speed for 5.0 minutes. The car's brakes are finally applied and stops in 2.0 minutes slowing evenly. The total distance traveled by...

You are traveling on a hilly road. At a particular spot, when your car is perfectly horizontal, the road follows a circular arc of some unknown radius. Your speedometer reads 90.0 km/h, and your apparent weight is 30% larger than usual. Use g-9.80 m/s2 for this problem. (a) Are you at the bottom of a hill or the top of a hill at that instant? the bottom of a hill the top of a hill There's not enough information to...

Please, CLEAR hand writing.
5) A boat is traveling in a rectangular lake (of dimensions 200 m along x axis and 150 m along y axis) along the diagonal direction shown with a velocity of 1 m/s. It has a thermocouple at its bottom with which it can measure the temperature of water. The temperature at the origin is 50 °C. As one moves along the x axis from the left shore to the right shore, the temperature increases linearly...

3 400 29. Water traveling along a straight portion of a river normally flows fastest in the middle, and the speed slows to almost zero at the banks. Consider a long straight stretch of river flowing north, with parallel banks 40 m apart. If the maxi- mum water speed is 3 m/s, we can use a quadratic function as a basic model for the rate of water flow x units from the west bank: f(x) x(40 – x). (a) A...

Chapter- 2. Kinematics in One-Dimension I. A car is traveling at 18. 5 m/s, and the driver notices that a traffic light just turned red. After the reaction time of the driver, 0.330 s later, the driver applies the brakes, and the car decelerates at 5.00 m/s2. Find the total stopping distance of the car, as measured from the point where the driver first sees the red light. (Hint: this distance is the sum of the two distances; one traveled...

PRACTICE IT Use the worked example above to help you solve this problem. A person measures the height of a building by walking out a distance of 49.1 m from its base and shining a flashlight beam toward the top. When the beam is elevated at an angle of 40.5° with respect to the horizontal, as shown in the figure, the beam just strikes the top of the building. Find the height of the building and the distance the flashlight...
