What is the new speed for an 10 kg object after 16500 N was applied to it for 2 seconds?

3300 m/s

F = ma; units: N = kg(m/s/s); where F and a are both vectors, while m, t, and v (speed) are scalars

We are given the mass, force, and the time; however, speed is our unknown.

[F = 16500 N]  [m = 10 kg]  [t = 2 s]  [v = unknown]

What we can do is use kinematics in order to relate v and t with F and m:

For example, we can use V = V₀ + at

Since F = ma can equal a = F/m, we can replace the a variable within the kinematics equation with F/m, so that:

V = V₀ + at

V = V₀ + (F/m)t

In this problem, we can assume the initial value V to equal 0, giving us:

V = (F/m)t

Plugging in the quantities we get:

V = · 2s

V = 3300 m/s

To further check whether this is the right manipulated equation to use, we can use dimensional anaylsis to determine that:

V = · s

V = m/s

I hope this helped!

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
