Answer 1

Answer:

In the above figure, Acceleration of bodies A, B and Care shown with directions. Values of b and c are w.r.t ground whereas a is acceleration of block A w.r.t Wedge C. Acceleration of block A w.r.t ground is

a)

\sqrt{ {(b + c)}^{2} + {a}^{2} }(b+c)2+a2

b)

c - (a + b) \cos(θ)c−(a+b)cos(θ)

c)

\sqrt{( {(b + c)}^{2} {c}^{2} - 2(b + c) c\cos(θ) }((b+c)2c2−2(b+c)ccos(θ)

d)

\sqrt{ {(b + c)}^{2} + {c}^{2} + 2(b + c)c \cos(θ) }(b+c)2+c2+2(b+c)ccos(θ)
