如图所示，一儿童玩具静止在水平地面上，一个幼儿用与水平面成53°角的恒力拉着它沿水平面运动，已知拉力F＝4.0N，玩具的质量m＝0.5kg，经过时间t＝2.0s，玩具移动了距离x＝4.8m，这时幼儿松开手，玩具又滑行了一段距离后停下来。（取g＝10m/s²，sin53°＝0.8，cos53°＝0.6）

（1）玩具在松手之前的加速度？

（2）全过程玩具的最大速度是多大？

（3）松开手后玩具还能滑行多远？

(A) 条件(1)充分，但条件(2)不充分．
(B) 条件(2)充分，但条件(1)不充分．
(C) 条件(1)和(2)单独都不充分，但条件(1)和条件(2)联合起来充分．
(D) 条件(1)充分，条件(2)也充分．
(E) 条件(1)和条件(2)单独都不充分，条件(1)和条件(2)联合起来也不充分．

A certain car dealership has two locations. Last month, an average (arithmetic mean) of 11 cars per salesperson was sold at location A and an average of 16 cars per salesperson was sold at location B. What was the average number of cars sold per salesperson at this dealership last month
(1) Last month, the number of salespeople at location A was 3 times the number of salespeople at location B.
(2) Last month, the total number of cars sold at location A was 132, and the total number of cars sold at location B was 64.
