Question

7 Block B starts from rest, block A moves with a constant acceleration,
and slider block C moves to the right with a constant acceleration
of 75 mm/s². Knowing that at t = 2 s the velocities of B and Care
480 mm/s downward and 280 mm/s to the right, respectively, deter-
mine (a) the accelerations of A and B, (b) the initial velocities of
A and C, (c) the change in position of slider block C after 3 s.​

Answer 1

Explanation:

:

photosynthesis is the process by which plants and some other organisms using sunlight, water, carbon dioxide, chlorophyll is called photosynthesis

Answer 2

Answer:

7 Block B starts from rest, block A moves with a constant acceleration,

and slider block C moves to the right with a constant acceleration

of 75 mm/s². Knowing that at t = 2 s the velocities of B and Care

480 mm/s downward and 280 mm/s to the right, respectively, deter-

mine (a) the accelerations of A and B, (b) the initial velocities of

A and C, (c) the change in position of slider block C after 3 s
