A bike going round a circular track whose radius is 63 m experiences an acceleration of 2.3 m/s^2. What is its velocity?*1 point1.2 m/s3.2 m/s4.8 m/s12 m/s

A car is speeding while travelling around a circular track of radius 65.0 m. At a particular point in time it has a speed of 40.5 m/s and an angular acceleration of 0.450 rad/s2. What is the total acceleration of the car at that point? 54.4 m/s2 25.2 m/s2 25.6 m/s2 38.6 m/s2

A stuntman drives a dirt bike on a curved track with a radius of 16.9 m. If he starts from rest and accelerates at 1.06 m/s2, at what time will the magnitude of the total acceleration of the bike be 5.74 m/s2? (Hint: the tangential acceleration will stay constant at 1.06 m/s2.)

A particle moves in a circle of radius 30 cm. Its linear speed is given by v = 2t, where t in second and v in m/s. Find out its radial and tangential acceleration at t = 3 s.A 220 m/s2, 50 m/s2 B 100 m/s2, 5 m/s2 C 120 m/s2, 2 m/s2 D 110 m/s2, 10 m/s2

A particle moves in a circle of radius 2.0 m at a speed given by v = 2t, where v is in ms–1 and t is in second. Find the magnitude of acceleration of particle at t = 1 s.Only one correct answerA.

A car is driving on a circular flat tarmac of radius R = 55 m (as shown below), starting from rest when t=0 seconds.The tangential component of the car’s acceleration as a function of time is represented by at = 0.5t m/s2.When t=6 seconds, determine the magnitude of the car's:(a) velocity, v = Answer m/s,(b) acceleration, a = Answer m/s2,(c) displacement, s = Answer metres.
