Suppose a cannon, placed on a moving cart with negligible friction in the wheel bearings, projects a cannonball straight up in the air. Would the vertical velocity of the ball as I see it as an observer be different from the vertical velocity as would be seen by the rider of the cart? How would you describe that motion, uniform velocity or uniform acceleration?

During football practice, a football is kicked with a speed of 22 m/s at an angle of 60.0° relative to the positive x direction. At that instant, an observer rides past the football in a car that moves with a constant speed of 11 m/s in the positive x direction. Complete the following statement: According to the observer in the car, the ball will follow a parabolic path. follow a straight line that is angled (less than 90°) with respect to the x direction. follow a path that is straight across in the +x direction. follow a path that is straight up and down in the y direction. follow a hyperbolic path.

A boat is trying to cross a river that is flowing to the right. In order to cross the river straight up, in which direction should the boat be directing itself? Down O Up-Left O Up O Up-Right

Water leaves a fireman’s hose (held near the ground) with an initial velocity v0 = 11.5 m/s at an angle θ = 30.5° above horizontal. Assume the water acts as a projectile that moves without air resistance. Use a Cartesian coordinate system with the origin at the hose nozzle position, as shown. 1). Using v0, θ, and g, write an expression for the time, tmax, the water travels to reach its maximum vertical height.  2)
