Which graph best represents the relationshin between the acceleration of an object falling Ireelynear the surface of Earth and the time that it falls?A)B)TimeTimeD)TimeTime3. An object is dropped from rest and falls freely 20.meters to Earth. When is the speed of the object 9.8meters per second?6. A child, starting from rest at the top of a playgroundslide, reaches a speed of 7.0 meters per second atthe bottom of the slide. What is the vertical heightof the slide? [Neglect friction.]A) during the entire first second of its fallB) at the end of its first second of fallC) during its entire time of fallD) after it has fallen 9.8 metersB) 1.4 mD) 3.5 mA) 0.71 mC) 2.5 m4. A 4.0-kilogram rock and a 1.0-kilogram stone fallfreely from rest from a height of 100 meters. Afterthey fall for 2.0 seconds, the ratio of the rock'sspeed to the stone's speed is7. A ball is thrown vertically upward with an initialvelocity of 29.4 meters per second. What is themaximum height reached by the ball? [Neglectfriction.]B) 29.4 mD) 88.1 mA 14.7 mВ) 1:2C) 2:1D) 4:1C)44.1 mA) 1:15. Objects A and B are dropped from rest near Earth'ssurface. Object A has mass m and object B has mass2m. After 2 seconds of free fall, object A has a speedv and has fallen a distance d. What are the speedand distance of fall of object B after 28. A book of mass m falls freely from rest to the floorfrom the top of a desk of height h. What is the speedof the book upon striking the floor?C) mgh D) mhA) zeh B) 24h9. A baseball dropped from the roof of a tall buildingtakes 3.1 seconds to hit the ground. How tall is theseconds of free fall?A) speed = v/2; distance = d/2B) speed = v; distance = dC) speed = v/2; distance = 2dD) speed = 2v; distance = 2dbuilding?
