Question

BlackTom AI · Accepted Answer

Restating the problem: A tennis racquet applies a constant force of 133 N on a ball for 0.035 s. We need the impulse delivered to the ball, to one decimal place.
Step 1: Recall the impulse–momentum relation: impulse I = F × Δt when the force is applied over a time interval Δt. Here, F = 133 N and Δt = 0.035 s.
Step 2: Multiply the force by the contact time: 133 N × 0.035 s.
Step 3: Compute the product: 133 × 0.035 = 4.655.
Step 4: Consider units: Newton-seconds (N·s) are the units of impulse, equivalent to kg·m/s.
Step 5: Apply rounding to one decimal place as requested: 4.655 rounds to 4.7 when rounded to one decimal place.
Step 6: Interpret the result: The impulse imparted to the ball is 4.7 N·s (to one decimal place).
