LAB 5: MORE ABOUT NEWTON'S LAWS Question 7: A cart is moving toward the right and speeding up at a steady rate, as shown in the diagram below. Imagine that arrows are drawn above the cart representing the magnitudes and directions of the net force on the cart at t=0s, t=1s, etc. Assume that the cart is already moving at - 1-9 6-4 4-2 4-3 " Positive direction A. What is the direction of the force vector att 2s? Explain. B. What is the sign of the force att 2s? Explain. C. Compare the magnitude of the force vector at t 2s to that at t 3s.
