2. A toy car with a mass of 35g (0.035kg) is moving clockwise around a loop-the-loop (a track in the shape of a circle that causes the toy car to travel along a circular trajectory) with a radius of...
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 student is riding their bike when they come across a turn in the form of a circular arc of radius R 3.0m as pictured in the diagram below and travel along this arc in the clockwise direction. At one point along this trajectory (the origin of the given coordinate system) it makes sense to define the Cartesian coordinate system shown where the x-axis is tangent to the trajectory and the y-axis is perpendicular to it. At this point the...
A toy car of mass 200 g is moving on a circular path of radius 20 cm at a constant speed v. It takes 8 s to complete one circle. What is the centripetal force, acting on the car? The answer is .024 N, I am only interested in the explanation of the problem. (if its just formulas its fine, just name each variable)
A car is travelling around a horizontal circular track with radius r = 270 m. It takes the car t = 66 s to go around the track once. The angle theta A = 19 degrees above the x axis, and the angle theta B = 56 degrees below the x axis. 1) What is the magnitide of the car? 2) What is the x component of the car's velocity when it is at point A? 3) What is the...
A car is traveling around a horizontal circular track with radius r 190 m at a constant speed v angle θ' 29" above the x axis, and the angle es* 65° below the x axis. 15 m/s as shown. The 1) What is the magnitude of the car's acceleration? m/s Submit 2) What is the x component of the car's acceleration when it is at point A m/s Submit 3) What is the y component of the car's acceleration when...
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...
please answer all A car is going with a constant tangential acceleration (i.e. increasing speed) in a circular path. As seen from above, the path is counter-clockwise. It crosses the point 'A' at time 0.00, at which point its speed is known. Find the direction of its centripetal acceleration at some time after it crosses the point A:Write your answer in degrees. Given: Speed when it crosses point 'A' - V-3.6 m/s, tangential acceleration a 3.6 m/s2, radius of path...
2. A car is driving at constant angular speed along a 20 m radius circular track. The car completes one revolution of the track in 10 seconds. Calculate: (i) The (tangent) speed of the car. 12.6 m/s (ii) The angular speed of the car. 0.63 1/s or 0.63 rad/s (iii) The centripetal acceleration of the car. 7.9 m/s2 (iv) The RPM (i.e. revolutions per minute) of the car. 6 RPM THE ANSWERS ARE IN BOLD, COULD YOU PLEASE SHOW THE...
P6 A car travels around a circular track at constant speed, as shown. It is observed that the car takes 15.71 seconds to go from point A to point B along the track (exactly a quarter circle). An accelerometer mounted on the car shows that its acceleration has a constant magnitude of 7.0 m/s2. Please answer each of the following questions. For answers that require vectors, refer to the instant shown in the figure. a) What is the radius of...
