A car travels at 67.5 km/h on a level road in the positive direction of an x axis. Each tire has a diameter of 72.2 cm. Relative to a woman riding in the car and in unit-vector notation, what are the velocity at the (a) center, (b) top, and (c) bottom of the tire and the magnitude a of the acceleration at the (d) center, (e) top, and (f) bottom of each tire? Relative to a hitchhiker sitting next to the road and in unit-vector notation, what are the velocity at the (g) center, (h) top, and (i) bottom of the tire and the magnitude a of the acceleration at the (j) center, (k) top, and (l) bottom of each tire?

A car travels due east with a speed of 35.0 km/h. Raindrops are falling at a constant speed vertically with respect to the Earth. The traces of the rain on the side windows of the car make an angle of 59.0° with the vertical. Find the velocity of the rain with respect to the following reference frames (a) the car (b) the Earth (a) To solve for the velocity of the rain relative to the car each moving relative to...

A car travels East at a constant velocity of 83 km/hr relative to the ground. A truck travels West at a constant velocity of 51 km/hr relative to the ground. What is the velocity of the truck relative to the car (enter the magnitude and direction separately)? Before you do any calculations, make sure that you draw a diagram that shows reference frames S and S'. Also, make sure that you label the velocities u, u', and v in your...

A car travels due east with a horizontal speed of 51.8 km/h. Rain is falling vertically with respect to Earth. The traces of the rain on the side windows of the car make an angle of 67.8◦ with the vertical. Find the magnitude of the velocity (km/h) of the falling rain before it hits the car. Hint: The three velocity vectors are (1) the velocity of the car with respect to the ground (horizontal), (2) the velocity of the rain...
