**Question:**A 47 g tennis ball is served at 45 m/s. If the ball started from rest, what impulse was applied to the ball by the racket?**Options:**- ○ 8.5 N·s- ○ 4.3 N·s- ○ 3.2 N·s- ○ 2.1 N·s- ○ 2.6 N·s**Explanation:**Impulse is the change in momentum of an object when a force is applied over time. It can be calculated using the formula:\[ \text{Impulse} = \Delta p = m \times \Delta v \]where \( \Delta p \) is the change in momentum, \( m \) is the mass, and \( \Delta v \) is the change in velocity.In this example, the mass \( m \) of the tennis ball is 47 g or 0.047 kg, and the change in velocity \( \Delta v \) is 45 m/s \((45 \, \text{m/s} - 0 \, \text{m/s})\).Calculating impulse:\[ \text{Impulse} = 0.047 \, \text{kg} \times 45 \, \text{m/s} = 2.115 \, \text{N·s} \]Therefore, the correct answer is approximately:- ○ 2.1 N·s

Given data: Mass (m) = 47 g = 0.047 kg Final velocity (Vf) = 45 m/s Initial velocity (Vi) = 0 m/s…

During a neighborhood baseball game in a vacant lot, a particularly wild hit sends a 0.149 kg baseball crashing through the pane of a second-floor window in a nearby building. The ball strikes the glass at 14.1 m/s, shatters the glass as it passes through, and leaves the window at 11.3 m/s with no change of direction. Calculate the magnitude of this impulse (a positive number). The ball is in contact with the glass for 0.0104 s as it passes through. Find the magnitude of the average force of the glass on the ball (a positive number).
