The Young’s modulus of polythene is 0.8
Answer:
I think that's Newton's second law of motion
Explanation:
f = m(v-u)
________
t
since a = (v-u)t
f = ma
Answer:
tan is 15 for that triangle
Answer:
B) the change in momentum.
Explanation:
The impulse is defined as the product between the force applied on an object (F) and the duration of the collision (
):
(1)
We can rewrite the force by using Newton's second law, as the product between mass (m) and acceleration (a):

So, (1) becomes

Now we can also rewrite the acceleration as ratio between the change in velocity and change in time:
. If we substitute into the previous equation, we find

And the quantity
is equivalent to the change in momentum,
.
