Will give brainliest! A motorboat heads directly across a 600 m wide river with a velocity of 12 m/s
and a current of 3 m/s is flowing south (at 270 degrees) in the river. How long does it take the boat to cross the river? (Answer in seconds) (v= x/t)

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
