A hypnotist suspends a clock from a piece of string and sways it in front of you. At the base of its trajectory (indicated in black), the clock is moving with speed 1.6 m/s. If the string has a length r = 0.14 m, and the clock has a mass of 0.18 kg, then what is the force of tension in the string when the clock reaches the base of its trajectory? Round your answer to the second decimal place
