15. A cart is uniformly accelerating from rest. The net force acting on the cart is (1) decreasing (2) zero (3) constant (4) increasing 16. If the mass of an object were doubled, its acceleration due to grav ity would be (1) halved (3) unchanged (4) quadrupled 17. What is the gravitational acceleration on a planet where a 2-kilogran (2) doubled mass has a weight of 16 newtons on the planet's surface? (1) % m/s2 (2) 8 m/s2 (3) 10 m/s2 (4) 32 m/s2
