A cart of mass m can move without friction on an airtrack. Initially, it is at rest. Then, for a limited time At, it is pushed down the track with a constant force F. Which of the following statements are true? True: The higher the mass of the cart, the harder you have to push to achieve the same final speed in the same amount of time. False: When you stop pushing, the cart starts slowing down again. True: While the cart is pushed, it has a constant acceleration. Computer's answer now shown above. You are correct. Previous Tries Your receipt no. is 151-8623 final speed. Leaving all other quantities unchanged, what happens in the scenarios below? If you double the force, you reach four times the If you push twice as long, you cover the same If you use a cart with half the mass, you reach If you push twice as long, you reach the same Submit Answer Incorrect. Tries 2/6 Previous Tries distance during pushing. final speed. double the final speed.
