(1)滑块沿圆弧从A到B运动过程中摩擦力对滑块做的功;
(2)若滑块不从右端滑离传送带,滑块与传送带的动摩擦因数μ应满足什么条件?
(3)若传送带与滑块的动摩擦因数μ=0.6,求滑块从B点开始到第一次离开传送带过程中产生的热量Q?

y = sin x, x∈R, y∈[–1,1],周期为2π,函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x, x∈[–1,1], y∈[–π/2,π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
