can I have the answer 1.A man goes on a walk and head east. He walk 4 km due east and 7 km due west. What is his final displacement assuming that east in the positive direction. 2. A car travels in a circle or radius 17 m for 4 minutes, during this time it make 3 revolutions, What is the speed in m/s?
3. A car with mass m travels over a hill with a radius of curvature of r at a speed of 15 m/s. What is the normal force on the car when the car is at the top of the hill? (6 pts) the car has a mass of 1200 Kilograms and the radius of curvature is 25 meters 4. A student with a mass of m rides a roller coaster with a loop with a radius of curvature of...
A car travels for 30 minutes at 30 m/s due North. The car stops for 10 minutes, then turns and travels for 20 minutes due south at 20 m/s. What is the average velocity of the car? What is the average speed of the car?
Can I have the answer please 1. A man goes on a walk and head east. He walk 0 km due east and 12 km due west. What is his final displacement assuming that east in the positive direction. 2.A car travels in a circle or radius 17 m for 4 minutes, during this time it make 3 revolutions, What is the speed in m/s? 3. This is a jeopardy type question. You must answer in the form of a...
A car travels at constant speed around a corner. The cars speed is 35 m/s and the radius of the circle is 0.25 km. The coefficient of static friction between the tires and the road is 0.7. What is the frictional force needed for the car to make the turn? What is the maximum force the static friction can produce? Does the car stay on the road? The car is in motion so why is the static friction important?
A car travels around a circle of radius r with constant speed. a. Is the velocity of the car constant? Explain. b. Is the car accelerated? Explain. c. Is there a net force applied to the car? Explain. d. If there is a net force applied to the car, in which direction does it point? If there is none, which of Newton’s Laws can be used to support the answer? Explain. e. Would your answers change for a different radius...
