Question

An object spins in a horizontal circle with a radius of 15.0 cm. The rotations are timed and the amount of time it takes for it to go around once is 0.56 s. The centripetal force is measured to be 6.1 N.According to the experiment, the speed of the object is closest to:'

Answer 1

Answer:

1.7 m/s

Explanation:

Relevant Data provided as per the question below:-

Radius = 15.0 cm

Time = 0.56 s.

Based on the above information

The computation of the speed of the object is shown below:-

$Velocity = \frac{2\times \pi \times Radius}{Time}$

$Velocity = \frac{2\times \frac{22}{7} \times 0.15}{0.56}$

$= \frac{0.942857}{0.56}$

= 1.683 m/s

or

= 1.7 m/s

Therefore for computing the speed of the object or velocity we simply applied the above formula by considering the pi and all other given data
