Answer:2.5 meters per second
Explanation:
10/4=2.5
Answer:
v=3.649 m/s
Explanation:
Lets start with the force of gravity on the elevator.
But the friction clamp opposes this with a force of 17000 N
So the Net force on the elevator is
Kinetic Energy
The motion will be describe
original Kinetic energy + work done = final kinetic energy + spring energy
Answer:
Explanation:
30 km/h b. 60 km/h c. 15 km/h d. 2 km/h. The answer is 15km/h. The rate will be the same. 30km / 2hr = _km / hr. By the law of equivalent fractions ...
Answer:
<em>a) 37.5N</em>
<em>b) 9.375Joules</em>
Explanation:
a) According to Hooke's law
F = ke
k is the spring constant
e is the extension;
F = 150 * 0.25
F = 37.5N
b) Work done on the spring = 1/2ke^2
Work done on the spring = 1/2 * 150 * 0.25^2
Work done on the spring = 75 * 0.0625
Work done on the spring = 9.375Joules
Answer:
I'M SORRY I CAN'T SEE THE PICTURE BUT IT WILL MOST LIKELY BE THE DIFFERENCE BETWEEN THE NUMBERS
Explanation:
for instance if there was someone pushing a desk with a net force of 9 towards the right, the net force would come to a total of 9 since there is no one on the other side pushing the desk. Meaning the desk would go right. I'm sorry if this isn't what you needed D:
