The final velocity is +15.0 m/s
Explanation:
The motion of the cart is a uniformly accelerated motion (=at constant acceleration), therefore we can use the following suvat equation:
where
v is the velocity at time t
u is the initial velocity
a is the acceleration
t is the time
For the cart in this problem, we have:
u = +3.0 m/s (initial velocity)
(acceleration)
t = 8.0 s (time)
Substituting, we find the final velocity:

Answer:
The components of reaction at the fixed support are
,
,
,
,
,
Explanation:
Looking at the diagram uploaded we see that there are two forces acting along the x-axis on the fixed support
These force are 400 N and [ i.e the reactive force of 400 N ]
Hence the sum of forces along the x axis is mathematically represented as
=>
Looking at the diagram uploaded we see that there are two forces acting along the y-axis on the fixed support
These force are 500 N and [ i.e the force acting along the same direction with 500 N ]
Hence the sum of forces along the x axis is mathematically represented as
=>
Looking at the diagram uploaded we see that there are two forces acting along the z-axis on the fixed support
These force are 600 N and [ i.e the reactive force of 600 N ]
Hence the sum of forces along the x axis is mathematically represented as
=>
Generally taking moment about A along the x-axis we have that
