“Answer the following questions for projectile motion on level ground assuming negligible air resistance (the initial angle being neither nor ): (a) Is the acceleration ever zero? (b) Is the acceleration ever in the same direction as a component of velocity? (c) Is the acceleration ever opposite in direction to a component of velocity?”“Answer the following questions for projectile motion on level ground assuming negligible air resistance (the initial angle being neither nor ): (a) Is the acceleration ever zero?
