Question

In a collision experiment, the ratio of the velocity change between two carts of equal inertia is found to equal 1.

Answer 1

Answer:

A) Therefore if I double the masses with are in the two terrine they are simplified and the radii of the speeds remain the same

B) If the masses are maintained and the speeds are doubled, the radius of the two speeds remains the same

Explanation:

A vehicle crash problem must be solved with the equation of the moment,

Initial instant Before crash

              p₀ = m v₁ + mv₂

After the crash

            $p_{f}$ = m $v_{1f}$ + m $v_{2f}$

           p₀ = $p_{f}$

If the speed ratio before and after the crash is one

           p₀ / $p_{f}$ = 1

We can assume that initially one of the cars was stopped

           m v₁₀ = m $v_{2f}$

           v₁₀ = $v_{2f}$

For the two speeds to be equal, the masses of the vehicles must be the same.

A) Therefore if I double the masses with are in the two terrine they are simplified and the radii of the speeds remain the same

B) If the masses are maintained and the speeds are doubled, the radius of the two speeds remains the same
