A rope is used to pull a 4.0 kg bucket of water upwards out of a deep well with an applied force 45 N. If starting from rest, what speed will the bucket have after experiencing this force for 2 seconds?

v = 22.5 m/s

Explanation:

The speed of the bucket can be found using the following equation:

Where:

: is the final speed =?

: is the initial speed = 0 (starts from rest)

a: is the acceleration

t: is the time = 2 s

We need to find the acceleration, it can be found as follows:

Where:

F: is the force = 45 N

m: is the mass = 4.0 kg

Now, the speed is:

Therefore, the speed that the bucket will have is 22.5 m/s.

I hope it helps you!

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
