1. An 800 kg car travels around the edge of a circular track of radius 400 m. At one point, the car accelerates around the track, increasing its speed from 40 m/s to 60 m/s over the course of 5 s. At the instant that the car reaches 50 m/s find (a) its angular velocity (b) its radial acceleration, (c) the centripetal force acting on the car, (d) the tangential acceleration of the car, and (e) the magnitude of the...
A bicyclist races once around a circular track of radius 265 m every 2.9 minutes at a constant speed. What is the bicyclist's acceleration in units of meters/second2?
25.1) Consider two identical cars travelling around a circular track. One car travels on an inside track and one on an outside track. Both cars complete a lap in the same amount of time. Which car has the highest kinetic energy? A) The outer car B) The inner car C) Both have the same KE 25.2) A solid disk and a flywheel (hoop) both have the same mass m, radius R, and angular velocity w. Which object has more kinetic...
A car with initial tangential speed of 10m/s accelerates on a circular track with radius of 100 m and with angular acceleration of 2 rad/s^2. How long it takes for the car to have its centripetal acceleration of 9 m/s^2? This is the question in verbatim.
You drive a car around a circular track of radius 50 m at a constant speed of 3 m/s, the centripetal acceleration magnitude (in m/s2 2.5 0.18 0.54 0.20
A car travels at a constant speed around a circular track whose radius is 2.65 km. The car goes once around the track in 341 s. What is the magnitude of the centripetal acceleration of the car?
A car travels at a constant speed around a circular track whose radius is 3.37 km. The car goes once around the track in 226 s. What is the magnitude of the centripetal acceleration of the car? I get 1.88 m/s^2
You try drive a car with mass 470kg at 40km/h around a circular track of radius 30m. A) What is the centripetal force on required to hold the car in this circular B) The track is banked at an angle of 12 degrees. What size is the friction force preventing the car sliding up the slope? C) If there is a coefficient of maximum static friction of 0.01, can you make the turn or will your car skid?
A car starts from rest and moves around a circular track of radius 32.0 m. Its speed increases at the constant rate of 0.550 m/s2. (a) What is the magnitude of its net linear acceleration 19.0 s later? (b) What angle does this net acceleration vector make with the car's velocity at this time? Question 6 A car starts from rest and moves around a circular track of radius 32.0 m. Its speed increases at the constant rate of 0.550...
