02e - Projectile Motion III

A golf ball is struck and given an initial horizontal velocity of 40 m/s at and angle of 30° above the horizontal. If the course if flat:

• the horizontal velocity of the ball on landing will be > 40 m/s

• the horizontal velocity of the ball on landing will be 0

• the horizontal velocity of the ball on landing will be 40 m/s

• the the horizontal velocity of the ball on landing will be < 40 m/s

What is the horizontal acceleration of a projectile?

• 0 m/s²
• 9.8 m/s²

• more than if it was just dropped
• less than if it was just dropped
• the same amount of time than if it was just dropped
• impossible to determine
