You are rolling on a skateboard with a constant velocity of 12 m/s. as you are moving you toss a baseball straight up into the air with a vertical speed of 25 m/s. how long will it take the ball to land back in your hand? how high will the ball go before it falls back down?

You are driving directly behind a pickup truck, going at the same speed as the truck. a crate falls from the bed of the truck to the road. (a) will your car hit the crate before the crate hits the road if you neither brake nor swerve? (b) during the fall, is the horizontal speed of the crate more than, less than, or the same as that of the truck?
