A 57 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? You stop the sled by pushing on it for 0.50 s in a direction opposite to its motion.
Initial momentum of the racket is zero, initial momentum of the ball is its speed times mass. The mass of a regulation tennis ball is 57 g (although it can vary slightly), and tests have shown that the ball is in contact with the tennis racket for 30 ms. A 57g tennis ball is served at 45m/s.
Initial Momentum Of The Racket Is Zero, Initial Momentum Of The Ball Is Its Speed Times Mass.
A strategic approach (3rd edition)… 3rd edition randall d. Earth is the object of reference. A 57 g tennis ball is served at 45 m/s.
0 6 = P R A C K E T − 6 ⋅ 0.
You stop the sled by pushing on it for 0.50 s in a direction opposite to its motion. You toss a tennis ball straight upward. Impulse = mv = 0.057kg x 45m/s = 2.565.
P = 2.565 Kgm/S Model Rocket Engines Are Rated By The Impulse That They Deliver When They Fire.
A 57g tennis ball is served at 45m/s. A tennis ball of mass 57.0 g is held just above a basketball of mass 590 g. A tennis ball of mass 57 g was moving horizontally at 68.4 m/s when it collided with a vertical racket that was a rest, after which it rebounded at 18.8 m/s.
A 57 G Tennis Ball Is Served At 45 M/S.
0 6, p r a c k e t = 0. A 57g tennis ball is served at 45m/s. A 57 g tennis ball is served at 45 m/s.
During A Serve, The Ball Typically Starts From Rest And Is In Contact With The Tennis Racquet For 30 Ms.
A particular engine is rated to deliver an impulse of 3.5 kg⋅m/s. A 57g tennis ball is served at 45 m/s? Given that the contact time between the ball and racket was 1/25 of a second, find the magnitude of the average impact force.
