An 85 kg object is moving at a constant speed of 15 m/s in a circular path, which has a radius of 20 meters. what centripetal force is exerted on the body?

Ihave a density of 1.61g/cm^3 and a mass of 28g. find the missing value

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
