22.(14分)如图所示,某滑板爱好者在平台上滑行,他水平离开平台边缘A点时的速度vA=4.0m/s,恰能无碰撞地沿圆弧切线从B点进入光滑竖直圆弧轨道,并沿轨道滑行.C为轨道的最低点,BD为轨道与水平地面的连接点.在滑到D点时,突然用力,使滑板变成沿水平地面继续滑行s=8.0m后停止.已知人与滑板可视为质点,其总质量m=60.0kg,沿水平地面滑行过程中所受到的平均阻力大小Ff=60N,空气阻力忽略不计,轨道半径R=2.0m,轨道BCD对应的圆心角θ =74°,g取10m/s2,cos37°=0.8,sin37°=0.6.求:

(1)人与滑板在B点的速度大小;

(2)运动到圆弧最低点C时对轨道的压力;

(3)人和滑板与水平地面在D点相互作用过程中损失的动能.
