1)An arrow with a suction cup on the end is fired at the back of a cart and sticks to it, causing the cart to rolls forward slowly. For all options take the cart and arrow as your system. Which of the following best describes this process. A)An elastic collision where both momentum and kinetic energy remain constant B)An elastic collision where only momentum remains constant. C)An inelastic collision where both momentum and kinetic energy remain constant D)An inelastic collision where only momentum remains constant
I need help answering this question
1)An arrow with a suction cup on the end is fired at the back of a cart and sticks to it, causing the cart to rolls forward slowly. For all options take the cart and arrow as your system. Which of the following best describes this process.
A)An elastic collision where both momentum and kinetic energy remain constant
B)An elastic collision where only momentum remains constant.
C)An inelastic collision where both momentum and kinetic energy remain constant
D)An inelastic collision where only momentum remains constant
2)An inelastic collision where only kinetic energy remains constantTwo clay balls are moving toward each other. The balls have equal kinetic energies (K1 = K2), but ball 1, which is coming from the left, is moving faster than ball 2 (v1 > v2). Which answer correctly explains how the balls will move after a totally inelastic collision?
A)The balls will move to the right because v1 > v2 before the collision
B)We cannot predict how the balls will move after the collision.
C)The balls will move to the left because p2 > p1 before the collision.
3)Two blocks, one with mass mm and the other with mass 2m2m are pushed by constant forces of equal magnitude FF over a distance of 1.0 m. Which of the following is true about the momentum of the two blocks at the end of this distance?
A) The 2m2m block has a larger momentum than the mm block
B)The momenta of the two blocks are equal
C)Not enough information
4)Two blocks, one with mass mm and the other with mass 2m2m are pushed by constant forces of equal magnitude FF over a time interval of 5.0 s. Which of the following is true about the kinetic energies of the two blocks at the end of this distance?
A)the mm block has more kinetic energy than the 2m2m block
B)The 2m2m block has more kinetic energy than the mm block
C)Not enough information
