(Will give brainliest) The values of the impulse and the time interval for various collisions are listed in the table. In which

igor_vitrenko [27]

Answer:

E) e

Explanation:

Impulse is equal to the product between the force applied (F) and the time interval of the collision ( $\Delta t$ ):

$I=F \Delta t$

This means that we can calculate the force for each collision dividing the impulse by the time interval:

$F=\frac{I}{\Delta t}$

Let's apply the formula to each case:

A) $F=\frac{10,000 kg m/s}{10^3 s}=10 N$

B) $F=\frac{1,000 kg m/s}{10^2 s}=10 N$

C) $F=\frac{100 kg m/s}{10^1 s}=10 N$

D) $F=\frac{10 kg m/s}{10^0 s}=10 N$

E) $F=\frac{1 kg m/s}{10^{-2} s}=100 N$

Therefore, the force is the maximum for collision E).

A ball is falling after rolling off a tall roof. The ball has

Rom4ik [11]

C.
Because it’s falling it has acceleration in the y direction. If you have acceleration, you usually also have velocity, and since kinetic energy is KE= Mv^2 you know you have it. It also has potential energy because it has some height to it, and PE= Mgh.
