Acar travels due east with a speed of 40.0 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 64.0° with the vertical. find the velocity of the rain with respect to the car and the earth. (enter the magnitude of the velocity.)

What is the order of the moon, earth, and sun in a lunar eclipse and a solar eclipse?

According to social exchange theory, altruistic behaviors benefit the individual who performs them. t/f

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2
