如图，有一半径为R=0.3m的光滑半圆形细管AB，将其固定在竖直墙面并使B端切线水平．一个可视为质点的质量为0.5Kg的小物体m由细管上端沿A点切线方向进入细管，从B点以速度V_B=4.0m/s飞出后，恰好能从一倾角为θ=37°的倾斜传送带顶端C无碰撞的滑上传送带．已知传送带长度为L=2.75m（图中只画出了传送带的部分示意图），物体与传送带之间的动摩擦因数为u=0.50，（取sin37°=0.60，cos37°=0.80，g=10m/s²，不计空气阻力，不考虑半圆形管AB的内径）．

（1）求物体在A点时的速度大小及对轨道的压力大小和方向；

（2）若传送带以V₁=2.5m/s顺时针匀速转动，求物体从C到底端的过程中，由于摩擦而产生的热量Q．
