Answer:
Clyde will provide greater impulse
Explanation:
We have given that Al exerts a force of 200 N for 5 sec
We know that impulse is given by, impulse = force ×time = 200×5 =1000 N-s
Bill exerts a force of 500 N for 2 sec
So impulse = 500×2 = 1000 N-s
Now the force exerted by Clyde 300 N for 4 sec
So impulse = 300×4 = 1200 N-s
From above calculation we can see that Clyde provide greater impulse than any other
Answer:
The object will have an upward acceleration
Explanation:
Let's consider the forces applied on the box. We have only two forces:
- The applied force of push, , downward
- The force of gravity, , (also known as weight of the object), downward
Therefore, the net force on the box is:
Here, we know that force applied is equal or greater than the weight, so
And therefore the net force is greater than zero:
(1)
According to Newton's second law of motion, the net force on the box is equal to the product between its mass and its acceleration:
where
m is the mass of the box
a is its acceleration
Given (1), this means that
Therefore, the box will have an upward acceleration.
In this case force example we have:
So the mass of the box is
So the net force is
And the acceleration is
I think the answer is Allele am not so sure of it and sorry if my answer is wrong or didn’t help okay
