Answer:

37.5 seconds

Explanation:

The given parameters are;

The mass of the block on the spring, m = 2.50 kg

The force with which the loaded spring launches the block, F = 450 N

The change in momentum of the block, Δp = 12.0 kg·m/s

We have;

Let the force with which the block was launched = The net force, F_{NET}

By Newton's second law of motion, we have;

F = F_{NET} = Δp × Δt

Where;

Δt = The time the block is in contact with the spring

Therefore;

\Delta t = \dfrac{F_{NET}}{\Delta p}

By plugging in the values for F_{NET} and Δp, we have;

\Delta t = \dfrac{450 \ N}{12.0 \ kg \cdot m/s} = 37.5 \ s

The time duration the block is in contact with the spring, Δt = 37.5 seconds.

A boat is traveling with a velocity of 18 meters/second relative to water and the river is flowing at a velocity of 2.5 meters/s
ddd [48]
Vt = Vboat - Vriver 
Vt = 18 - 2.5 = 15.5 m/s 

If the boat's direction is the same as the water, you sum the velocities of the river and the boat .

Explanation:

It'll be impossible for the project to be eligible for any other LT credits because it can't double dip.

Double dip refers to obtaining money from two sources at the same time or by two separate accounting methods.

This is often regarded, unethical.
