A piston motion moves a 25-kg hammerhead vertically down 1 m from rest to a velocity of 50 m/s in a stamping machine. What is th
Alja [10]

Answer:

31.005 KJ

Explanation:

We are given that

Mass of hammerhead=25 kg

Initial velocity,u=0

Final velocity,v=50 m/s

h=-1 m

h'=0

We have to find the change in total energy of the hammerhead.

Change in total energy=E_2-E_1=m(u_2-u_1)+\frac{1}{2}m(v^2-u^2)+mg(h-h')

Using the formula

Change in internal energy of hammerhead=m(u_2-u_1)=0

Change in total energy=\frac{1}{2}(25)(50)^2+25\times 9.8(-1)

Where g=9.8m/s^2

Change in total energy=31005 J=\frac{31005}{1000}=31.005 KJ

1 KJ=1000 J

What is the average acceleration of the object represented in the graph above over the 10 seconds? I know the answer isn’t C
polet [3.4K]

It's always a good idea to start with the definition of the thing you're trying to find.

This problem is just trying to find out whether you KNOW the definition of acceleration. You may know it, but you haven't used it yet.

Average acceleration = (change in velocity) divided by (total time).

Change in velocity = (end value) minus (start value)

Change in velocity = (20m/s) - 0

Change in velocity = 20 m/s

Time = 10 s

Average acceleration = (20m/s)/(10s)

Average acceleration = 2 m/s^2
