hi, i need answer on the questions below. please provide explanation or solution if needed so i can better understand it. thank youu!

20. Relate the two objects (A and B) that start at x = 0 at t =0 and move in one dimension independently of one another. The graphs of the velocity of each object vs. time are shown below. (A)Which moves with constant non-zero acceleration? Velocity (m/s) Velocity (m/s) I Time (3) Time ($) A. A B. B C. Both A and B D. Neither A nor B E. No Answer(B) Which object is in its initial position at t = 6 s? A. A B. B C. Both A and B D. Neither A nor B E. No Answer (C) Which object is farthest from the origin at t = 6s? Please take note that each interval on the x-axis is equivalent to 1 second, and 1 m/s for the y-axis. A. A B. B C. Same location D. Same Distance from the origin but in opposite directions. E. No Answer21. A car starts from rest and accelerates as shown in the graph below. At what time would the car be moving with the greatest velocity? Please take note that each interval on the x-axis is equivalent to 1 second, and 1 m/$^2 for the y-axis. Acceleration (m/s]] Time (s) A. 1.5 seconds B. 3 seconds C. 4.5 seconds D. 6 seconds E. No Answer22. A ball is speeding up along a circular track. What can be said about the velocity and acceleration vectors on the body? A. The velocity and acceleration vectors are parallel to each other. B. The acceleration vector is opposite in direction relative to the velocity vector C. There's a component of acceleration vector parallel to the velocity vector D. There's a component of acceleration vector anti-parallel to the velocity vector23. Please refer to the following vectors: A = 6i + 2j - 3k B = 3i - j - 2k C= -i+ j - 4k D = j - 3k E =-i+ 2k F = -5k G = 2i H = -3j 1 = -4i +4j Solve 5(1 x H) + 3*(B . C x E) A. Bi - 9j - 4k B. -61 -6j +54k C. 12i + 72j +5k D. -20i - 20j - 147k E. No Answer 24. Assume a one-dimensional motion along the z-axis. If the z-coordinate of the particle is negative and changing in an increasing manner, the particle must be: A. Moving towards the negative z-direction. B. Moving towards the negative x-direction. C. Moving towards the positive x-direction. D. Moving towards the positive z-direction. E. No
