Hope this helps. I think it should be right.
Answer:
sorry about the other person but its b
Explanation:
Answer:
1) 1.08 m/s^2
Explanation:
Acceleration is equal to the change in velocity divided by the time taken:
where
v is the final velocity
u is the initial velocity
is the time taken
In this problem, we have:
- initial velocity: u = 0 (you start from rest)
- final velocity: v = 5.4 m/s
- time taken:
Therefore, the acceleration is
2) -0.54 m/s^2
We can calculate the acceleration to slow down using the same formula as before, but this time the data are as follows:
- initial velocity : u = 5.4 m/s
- final velocity : v = 0 (you come to a stop)
- time taken :
using the same formula, we find
And the negative sign means it is a deceleration.
(A) The impeller blades are worn or slipping on the shaft
Answer:
the net force is greatest at the points where the acceleration is maximum.
the net force is zero at the points where the object is in equilibrium.
Explanation:
net force of any object is defined by Newton's second law i.e F=ma
so when the object has zero acceleration it will experience zero net force and when the object has maximum acceleration it will experience greatest net force say when the object is in a maximum unbalanced state.
