What is the velocity if your going 105 miles every 10 minutes

2 answers:

8 0

The speed is 10.5 miles per minute, or 630 miles per hour.
We don't know the velocity, because you didn't tell us anything about the direction I'm going.

Velocity= distance/time

Distance= 105
Time=10
Velocity= 105/10
Velocity= 10.5m/s

I need to know the solution and the formula.

scoray [572]

Statement:

A non-deformed spring is 15 cm long. When a 2.0 N force is applied to it, its length becomes 19 cm.

To find out:

The spring constant of the spring.

Solution:

Force (F) = 2 N

Extension of the spring (x)
= (19 - 15) cm
= 4 cm
= 0.04 m [since we have to find the answer in N/m]

Let the spring constant of the spring be k.

We know, the formula of spring force, i.e.,
F = kx

Putting the values in the above formula, we get
2 N = k × 0.04 m
or, k = 2 N ÷ 0.04 m
or, k = 50 N/m

Answer:

The spring constant of this spring is 50 N/m.

Hope you could understand.
