impulsive force model worksheet 3 answers

Observe how the water rises as the pebbles displace volume. Have students add pebbles at the right moment in the story. Students can bring their crows to the pitcher as the bird attempts to drink. Tell the story of The Crow and The Pitcher. Use a strip of electrical tape to mark the water level on the side of the jug. If this project is being done for a Science Fair, you could buy a puppet instead as that makes for better storytelling. A white crayon will stand out on the black paper to draw feathers, eyes, and beak details. Have students use construction paper, crayons, and scissors to draw and cut out images of crows. – A large measuring cup with graduated measurement lines There’s also a fun video I’ve made to go with this episode at my YouTube channel, starring myself, my daughter, and a very cute puppet.Īctivity: Volume Displacement as taught in “The Crow and The Pitcher” This fable also teaches about the concept of displacement in physics! Suppose that the golf ball was in contact with the floor for 4.0 x 10-4s.“The Crow and the Pitcher” by Aesop doesn’t just have a wholesome moral that teaches children to solve problems with resilence and creative thinking. 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.)Į. What will the instantaneous momentum of the golf ball be immediately before it strikes the floor? d. Determine the time required for the ball to reach the floor. Construct a motion map for the golf ball from the time it is dropped until it reaches its highest point of rebound. Perfectly elastic collision with the floor.Ī. A golf ball that weighs 0.45 N is dropped from a height of 1.0 m.

For how much time must the engine burn during the launch in order to reach this speed?ĥ. A rocket, weighing 4.36 x 104N, has an engine that provides an upward force of 1.2 x 105N. Modeling Instruction - AMTA 2013 2 U9 Momentum - ws 2 v3.1Ĥ. How large is the force the ball exerts on the bat? Explain. What is the final velocity of the ball? d. When the batter hits the ball, a net force of 1150 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 is v = 0.0 m/s, what will its speed be when it leaves the pitcher's hand? c. What is the magnitude of the change in momentum of the ball?ī. While being thrown, a net force of 132 N acts on a baseball (mass = 140 g) for a period of 4.5 x 10-2 sec. The following questions refer to the motion of a baseball.Ī. Justify your answer.ī) Find the value of the ratio of kinetic energy C to kinetic energy D. Object C has twice the velocity of object D.Ī) Find the value of the ratio of momentum C to momentum D. Two other objects, C and D, have identical masses. Justify your answer.ī) Find the value of the ratio of kinetic energy A to kinetic energy B. Object A has 3 times the mass of object B.Ī) Find the value of the ratio of momentum A to momentum B. Two objects, A & B, have identical velocities.
