- Please Asap1. A wheel is spinning so that it goes around 6 times every second. A brake is then applied to the wheel, causing it to slow to a frequency of 3 times per second in 5 seconds. How many times does the wheel spin around while the brake is applied? Fill in the table with what is given and what is needed. All values in the table should be in terms of radians. ΔΘ @i Of а At XA disk spins at 4.0 revolutions/second. What is its period, in second? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
