Carol wants to move her 32 kg sofa to a different room in the house. She places “sofa sliders,” slippery disks with μk = 0.080, under the feet of the sofa. She then pushes the sofa at a steady 0.40 m/s across the floor. How much force does she apply to the sofa?
Scientists are experimenting with a kind of gun that may eventually be used to fire payloads directly into orbit. In one test, this gun accelerates a 7.6-kg projectile from rest to a speed of 5.1 × 103 m/s. The net force accelerating the projectile is 6.4 × 105 N. How much time is required for the projectile to come up to speed?
