A toy car starts at rest on a circular track of radius 2.30 m. If it uniformly increases speed to 1.70 m/s in 3.10 seconds, find the magnitude of the acceleration of the car at the very end of the trip.
v = 1.7 m/s
R = 2.3 m
t = 3.1 sec
Centripetal Acceleration = Tangential Acceleration
a(c) = a(t) = v^2/R = 1.7^2/2.3 = 1.26 m/s^2

(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...
A test car starts from rest on a horizontal circular track of 80 m radius and increase its speed at a uniform rate to reach 100 Km/h in 10 seconds. Determine the magnitude of total acceleration of the car 8 seconds after the start . Rotation of the radially slotted arm is governed by 0-0.21 + 0.02r, where 0 is in radians and t is in seconds. Simultaneously, the power screw in the arm engages the slider B and controls...
A race car starts from rest on a circular track. The car increases its speed at a constant rate a; as it goes once around the track. Find the angle that the total acceleration of the car makes- with the radius connecting the center of the track and the car- at the moment the car completes the circle.
(9.2.70) A car drives around a circular track of radius 50 m. The car starts at rest at time t = 0, and its speed increases at a rate of 3.00 m/s. (a) Draw a top view illustrating the motion of the car around the circle, and also a side view showing a free-body diagram for the car (b) Find an equation which gives the magnitude of the net acceleration vector as a function of time (incorporating both radial and...
