Question

A toy radio-controlled car races around a circular track in a time of 2 MINUTES, with a speed of 5.25 m/s. What is the radius of the
circular track? (will give brainliest)

Answers

  1. Answer:

    The radius will be “100.31 m”. A further solving is given below.

    Explanation:

    The given values are:

    Time,

    T = 2 minutes

    i.e.,

     = 120 seconds

    Speed,

    V = 5.25 m/s

    As we know

    ⇒  T=\frac{2 \pi R}{V}

    then,

    ⇒  R=\frac{TV}{2 \pi}

    On substituting the given values, we get

    ⇒      =\frac{120\times 5.25}{2\times 3.14}

    ⇒      =\frac{630}{6.28}

    ⇒      =100.31 \ m
