What was the average force on the ball while it was in contact with the floor? FΔt = mΔv F = (mΔv)/ Δt (0.045kg)(8.94m/s)/(4.0x10-4s) = 1005.Complete Force and Motion Bundle (inclusive of over 18 Worksheets)Ī complete bundle consisting of a presentation slide with 125 slides abundant with pictures, equations, examples and exercises to ensure a holistic understanding of motion, force, momentum, energy, power and springs! Coupled with 18 worksheets totaling to over 300 questions. Suppose that the golf ball was in contact with the floor for 4.0 x 10-4s. A force of 20 physicsclassroom com, impulsive force model worksheet 4 a solutions, momentum fr exam review docx document, name answer key conservation of momentum i yola, momentum the elusive difference between force and, impulse momentum worksheet 3 course hero, collection of impulsive force model worksheet 4, 0 km in 22 minutes, and finally 1. What will be the change in momentum, (p) from the instant before the ball collides with the floor until the instant after it rebounds from the floor? (Illustrate with a vector diagram.) Δρ = (0.045 kg)(4.47m/s-(-4.47m/s)) = 0.4023 kg-m/s e. What will the instantaneous momentum of the golf ball be immediately before it strikes the floor? vf = at + vi vf = 10m/s2*0.45s = 4.47m/s 0.045kg(4.47m/s) = 0.20 kg-m/s d. Determine the time required for the ball to reach the floor. In the margin, construct a motion map for the golf ball from the time it is dropped until it reaches its highest point of rebound. 3 Worksheets with over 30 questions extensively covering the principle of conservation of momentum, elastic collision, inelastic collision, explosion, frinctional force, balanced forces, impulse and impulsive force. Assume that the golf ball has a perfectly elastic collision with the floor. How long must the engine burn in order to reach this speed?įΔt = mΔv 104 N) Δt = 4.36 x 103 N*860m/s Δt = 4.43sĪ golf ball that weighs 0.45 N is dropped from a height of 1.0 m. Draw a force diagram for the rocket.įg b. A rocket, weighing 4.36 x 104 N, has an engine that provides an upward force of 8.90 x 105 N. Object A has 3 times the mass of object B. What force does the ball exert on the bat in the question above? Explain. Impulsive Force Model Worksheet 2: Impulsive Forces and Momentum. What is the change in momentum of the ball? What is the final velocity of the ball? (use initial velocity from #4) FΔt = impulse = momentum = mΔv 1320N*(9.0x10-3 s) = 11.88 N-s = (0.140kg)Δv Δv = 84.9 m/s = vf –vi = 84.9m/s = vf – (- 42.4m/s) = + 42.5 m/s 6. When the batter hits the ball, a net force of 1320 N, opposite to the direction of the ball's initial motion, acts on the ball for 9.0 x 10-3 s during the hit. If the initial speed of the baseball in question 3 is v0 = 0.0 m/s, what will its speed be when it leaves the pitcher's hand? FΔt = impulse = momentum = mΔv 132N*(4.5x10-2 s) = 5.94 N-s = (0.140kg)Δv Δv = 42.4 m/s 5. What is the magnitude of the change in momentum of the ball? FΔt = impulse = momentum = mΔv 132N*(4.5x10-2 s) = 5.94 N-sĤ. While being thrown, a net force of 132 N acts on a baseball (mass = 140g) for a period of 4.5 x 10-2 sec. Object C has twice the velocity of object D. Two other objects, C and D, have identical masses. Two objects, A & B, have identical velocities.
