Answer:

C. -15m/s

Explanation:

using formula, v = u + at

where v = final velocity

u = initial velocity = 0

a = acceleration = -3m/s/s

t = time = 5sec

=> v = 0 + -3×5 = -15m/s

Vinvika [58]

Answer:

Speed is a scalar quantity that refers to "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time.

Explanation:

The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time.

If Pressure = 1000 Pa and Area = 0.2 m square, then Force

Maksim231197 [3]

Here

Pressure=1000Pa

Area=0.2m Square

Force=?

Now,,

Pressure =force / Area

1000=force/0.2

force=1000/0.2

Therefore,Force=5000N
