Answer:
Equal
Explanation:
The impulse theorem states that the impulse exerted on each cart is equal to the change in momentum of the cart:
where
I is the impulse
pf is the final momentum
pi is the initial momentum
The impulse is equal to the product between the force applied and the contact time:
In this case, the force applied to the two carts (F) is the same, and the contact time (
) is the same as well. Therefore, the impulse exerted on the two carts is the same.
Moreover, the initial momentum of the two carts is also the same (zero, because they start from rest: 
). So the formula becomes
And since I is the same for the two carts, the final momentum (
) will also be equal.
Answer:
the impact on the water varies from different heights, therefore the mass stays the same, yet the force on the water increases from a higher height. A taller height will produce a bigger splash!
Explanation:
Answer:
Explanation:
a )
Moment of inertial of four masses about axis that coincides with one side :
Out of four masses . location of two masses will lie on the axis so their moment of inertia will be zero .
Moment of inertia of the two remaining masses
= m L² + m L²
= 2 mL²
b )
Axis that bisects two opposite sides
Each of the four masses will lie at a distance of L / 2 from this axis so moment of inertia of the four masses
= 4 x m x ( L/2 )²
= 4 x mL² / 4
= m L² .
They are transverse and travel at the speed of light.
