In T-ball, batters hit a ball that is placed on a T-shaped stand. Batter A hits the ball by swinging the bat from a resting position on his shoulder. Batter B hits the ball with the bat directly behind it. In one or two sentences, create and justify a claim about which batter will likely hit the ball the greater distance. (2 points)
Batter A will likely hit the ball a greater distance because swinging the bat from a resting position on his shoulder allows for a longer swing and therefore, more power behind the hit.
Batter B is likely to hit the ball a greater distance because hitting the ball directly behind it allows for a more powerful and efficient transfer of energy from the bat to the ball, resulting in a higher exit velocity.
The claim is that Batter B is likely to hit the ball a greater distance because hitting the ball directly behind it allows for a more efficient transfer of power from the bat to the ball, resulting in a stronger and longer hit. This claim is justified based on the principle of angular momentum and the physics of bat-ball collisions.
A musician hits a drum with a drumstick. In three to four sentences, explain the collision forces between the drum and drumstick. (4 points)
When a musician hits a drum with a drumstick, there are primarily two types of collision forces at play. Firstly, there is an impact force exerted by the drumstick on the drum's surface upon contact, which causes the drumhead to vibrate and produce sound. This force is responsible for the audible output of the drum hit. Secondly, there is a reactive force exerted by the drum in response to the impact force, known as the normal force. The normal force acts in the opposite direction of the impact force, balancing it out and allowing the drumstick to rebound back after impact. This force is crucial for the musician to maintain control and rhythm while playing the drums.
When a musician hits a drum with a drumstick, there is an impact force exerted by the drumstick on the drum's surface, causing it to vibrate and produce sound. Simultaneously, there is a reactive force exerted by the drum that allows the drumstick to rebound back after impact, maintaining control and rhythm.
