Question
A 0.13-kg ball moving in a circle at the end of a string has a centripetal acceleration of 1 m/s^2. What is the magnitude of the centripetal force exerted by the string on the ball to produce this acceleration? A car with a mass of 940 kg is moving around a curve with a radius of 30 m at a constant speed of 40 m/s (about 89 MPH). (a) What is the centripetal acceleration of the car? (b) What is the magnitude of the force required to produce this centripetal acceleration? A car with a mass of 1200 kg travels around a banked curve with a constant speed of 34 m/s (about 76 MPH). The radius of curvature of the curve is 40 m. a) What is the centripetal acceleration of the car? (b) What is the magnitude of the horizontal component of the normal force that would be required to produce this centripetal acceleration in the absence of any friction?Explanation / Answer
1.
the centripetal force is calculated as follows:
F = mac
= 0.13*1
= 0.13 N
