A) Impulse is greater on concrete
B) Impulse is less on the grass
C) Both A and B
D) Neither. Impulses are the same

Two balls of equal size are dropped from the same height from the roof of a building. One ball has twice the mass of the other. When the balls reach the ground, how do the kinetic energies of the two balls compare? a - The lighter one has one fourth as much kinetic energy as the other does. b - The lighter one has one half as much kinetic energy as the other does. c - The lighter one has...
3. Two identical balls leave from the same height at position 1 & 2 with the same speed but at different angles. When two balls come back to the same height again (at position 3), what is NOT the same for both balls? A. Acceleration B. Potential energy C. Kinetic energy D. Momentum 1 2 3 4. Two balls of equal mass are thrown horizontally with the same initial velocity. They hit identical stationary boxes resting on a frictionless horizontal...
one-dimensional movement exercise: Two balls are dropped in a vacuum from the same height, but at different times; The second ball hits the ground 1.35 seconds after the first hits the ground. A. from the above information, deduce an expression that allows you to find the difference between your heights (∆h = h2-h1)
Two identical objects are dropped from rest at the same time. Object A is dropped from twice the height of object B. If there is no air resistance, which statement is true? None of the answers given is true. Both objects hit the ground at the same time. Object A takes twice the time to fall as object B. Object A takes four times the time to fall as object B.
a) A super ball of mass 0.05kg is dropped from a height of 10 cm above a table top. It bounces off the table and rises to the same height. Sketch the shape of the force exerted on the ball by the table as a function of time. (time vs force). If the superball was in contact with the table for 30 ms, what is the average force exerted on the ball by the table? b) The superball is replaced...
: Two objects, one having three times the mass of the other, are dropped from the same height in a ... (1 bookmark) Two objects, one having three times the mass of the other, are dropped from the same height in a vacuum. At the end of their fall, their velocities are equal because: Entry field with incorrect answer a) anything falling in vacuum has constant velocity b) all objects reach the same terminal velocity c) the acceleration of the...
Can anyone explains all the answers? Two balls, A and B are thrown at the same angle above horizontal, but initial velocity of ball A is two times greater than initial velocity of ball B. Ignore air resistance. we can conclude that horizontal range covered by ball A is same as range covered by ball B twice the range covered by ball B four times the range covered by ball B. greater than horizontal range covered by ball b, but...
1. Two metal balls (A and B) are the same size, but ball A has a mass of 20 kg and ball B has a mass of 10 kg. Ball A is dropped from a height of 100 meters above the Earth in a vacuum (so that we can ignore air resistance). 1 second later Ball B is dropped from the same location. While they both are falling, which has a greater gravitational force acting on it? Explain.
Liam throws a ball horizontally with a large force at a height of 1 m from the ground. At the same time, Lily drops another identical ball from the same height. Which of the two balls hits the ground first? The ball dropped by Lily Depends on the amount of force used by Liam. Neither - they both hit the ground at the same time. The ball thrown by Liam.
Two identical objects start at the same height above level ground. Simultaneously, object A is dropped and object B is launched horizontally with a speed of 20 m/s. Assume that air resistance is negligible. a) Which object hits the ground first, or do they hit the ground at the same time? b) Which object hits the ground with the greatest speed, or do they hit the ground with the same speed? c) If the two objects started at a height...
