-40 m/s in steps of -10 m/s every second; hence, approximately 8 seconds elapse during the motion. The velocity acceleration in the horizontal direction is zero. Therefore, the displacement of the ball in the r-di given by the equation,ax vort (20 m/s)(8 s) = 160 m. vector constantly changes direction, but the horizontal velocity never changes because the LEARN MORE REMARKS problems This example emphasizes the independence of the x- and y-components in projectile motion QUESTION How does the magnitude...
A cart is moving horizontally along a straight line with constant speed 30 m/s.
Problem 12:A cart is moving horizontally along a straight line with constant speed 30 m/s. A projectile is to be fired from the moving cart in such a way that it will return to the cart after the cart has moved 80m. At what speed (relative to the cart) and at what angle (to the horizontal) must the projectile be fired?NOTE: remember that to calculate the speed of the projectile respect to the cart, we need to subtract the velocity...
