A 1200 kg car is being towed to the shop. The tow truck applies 3200 N of force in order to keep the car moving at a constant velocity. (Friction is present.) What is the Horizontal Fnet and Vertical Fnet? Also determine the coefficient of kinetic friction between the car's tires and the road.

Atransverse wave is traveling on a string stretched along the horizontal x-axis. the equation for the vertical displacement y of the string is given by y = (1.8 x 10-3)cos[π(13x - 60t)], where all quantities are in si units. what is the maximum speed of a particle of the string

Ineed the answer to question 1 , i’m desperate
