2. If a particle starts from rest and accelerates according to the graph shown, the particle's velocity at t= 20 s is a 200 m/s b100 m/s C. 0 d. 20 m/s 3. The particle in Problem 2 stops moving at t= 10 s a. b. C. d. 40 s 20 s 30 s ww +76) -plz help

Dynamics: Particle kinematics Block B moves downward with a constant velocity of 20 mm/s. At t = 0, block A moves upward with constant acceleration and its velocity is 30 mm/s. If it is known that at t = 3 s the sliding block C has moved 57 mm to the right, determine: (a) the velocity of the sliding block C at t = 0. b) the accelerations of A and C c) the change in the position of block A after 5 s.

The Option B is correct I need handwritten solution with FBD within 30min [Don't copy similar solution available]

a rock thrown vertically upward from the surface Of the moon as a velocity of 24 m/sec reaches a height of S(t)- 24t -0.t*m in t seconds. 2.
