Abox of mass 17.6 kg with an initial velocity of 2.25 m/s slides down a plane, inclined at 19◦ with respect to the horizontal. the coefficient of kinetic friction is 0.48. the box stops after sliding a distance x. 17.6 kg µk = 0.48 2.25 m/s 19◦
how far does the box slide? the acceleration due to gravity is 9.8 m/s 2 . the positive x-direction is down the plane. answer in units of m.

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.
