Force (number of rubber bands) 14. | A constant force applied to object A causes it to accelerate at 5 m/s. The same force applied to object B causes an acceleration of 3 m/s. Applied to object C, it causes an acceleration of 8 m/s a. Which object has the largest mass? b. Which object has the smallest mass? c. What is the ratio of mass A to mass B (mA/mB)? 24. || INT In t-ball, young players use a bat to hit a stationary ball off a stand. The 140 g ball has about the same mass as a baseball, but it is larger and softer. In one hit, the ball leaves the bat at 12 m/s after being in contact with the bat for 2.0 ms. Assume constant acceleration during the hit. a. What is the acceleration of the ball? b. What is the net force on the ball during the hit? 26. || The IKAROS spacecraft, launched in 2010, was designed to test the feasibility of solar sails for spacecraft propulsion. These large, ultralight sails are pushed on by the force of light from the sun, so the spacecraft doesn't need to carry any fuel. The force on IKAROS's sails was measured to be 1.12 mN. If this were the only force acting on the 290 kg spacecraft, by how much would its speed increase after 6 months of flight? 4: Forces and Newton's Laws of Motion AV - 34. || Your car is skidding to a stop from a high speed. 35. || Your physics textbook is sliding across the table. 36. || An ascending elevator, hanging from a cable, is coming to a stop. 38. | You hold a picture motionless against a wall by pressing on it, as shown in Figure P4.38.
