Two balls are released from the same height on the moon. They both reach the ground at the same time. Which statement is correct about the two balls?
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...
two balls that are set to be collide elastically, give these two balls specific masses and initial velocity. The balls cannot have the same mass, and they must be moving in both the x- and y-directions. These are the data: Mass for ball 1=3kg Mass for ball 2=5kg Initial velocity ball 1=1.50 Initial velocity ball 2=2.0 Use Conservation of Momentum in x and y, as well as Conservation of Energy, to determine the final velocities of the balls after the...
You notice two balls rolling down a hill. Both balls were initially at rest, both have the same mass and same radius, but one of them is clearly rolling down faster than the other. What could explain this?
The balls have a mass of 1 gram and are 2. Two small balls are both positively charged. suspended from strings such that they repel. Use the diagram below to estimate the charge on each ball (assume they have the same charge). 192 170 15 cm 92 91 17 for
Two marbles are released from the same height. The first marble is released at time t = 0; the second marble is released at a later timet- (a) At timet i, what is the difference in the speeds of the two marbles? (you may use g to represent the magnitude of the acceleration of gravity.) (b) For times t is the difference in speeds larger, smaller or the same as the difference in the speeds in part (a)? (c) At...
Given 12 balls with the same diameter and color. They all have the same weight, except one of them which can be lighter or heavier. Show how to identify the ball with different weight with a balance. Any number of balls can be placed on both sides of the balance. Your goal is to design a procedure to identify the ball with different weight in 3 measurements. Can you do it with 2 measurements? Justify your answer.
QUESTION 4 Suppose you throw two balls B1 and B2 vertically upward. The maximum height to which ball B1 rises is twice that of ball B2. When in the air moving upward: O [a] The magnitude of acceleration of ball B1 is greater than that of ball B2. O [b] The acceleration of both balls is same in magnitude and points upward. [c] The acceleration of both balls is same in magnitude and points downward.
Two small identical clay balls of mass m are suspended from the same point by strings of length L. One of them is pulled sideways and up such that its string makes an angle ? as shown. After being released from rest, it collides with the other ball, and they remain stuck together after the collision. How high h will the two balls rise after the collision? Enter your symbolic answer as a function of m, L, g, and theta...
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 (such as billiard balls) have a one-dimensional collision in which one is initially motionless. After the collision, the moving object is stationary and the other moves with the same speed as the other originally had. Show that both momentum and kinetic energy are conserved.
