N9T.1 You are driving 5 ft or so behind a pickup truck (don't actually try such a stupid tailgating stunt, of course!). A jostled crate tips off the back of the truck with only a very small backward velocity. The crate will not hit your car until after it hits the road, regardless of your speed. True (T) or false (F)? (Ignore air resistance.)
As a projectile moves along its parabolic trajectory, which of the following remain constant (ignoring air resis- tance, and defining the z axis as pointing upward)? A. Its speed B. Its velocity C. Its x-velocity and y-velocity D. Its z-velocity E. Its acceleration Screenshot 2021-10-30 at 12.06.3 f. Its x-velocity, y-velocity, and acceleration T. Some other combination of the given quantities
