Calculate the speed of a 2-kg ball that has momentum of 10 kg•m/s

1 answer:

7 0

The formula for momentum is:
M=Mass*Velocity

From this formula we can derive the formula for velocity:

V=Momentum/Mass

We already know momentum (10 kg m/s) and mass (2 kg). Let's plug in the numbers into the formula:

V=10/2
V=5 m/s

Find the distance between the two points.

Ksenya-84 [330]

Hey there!

Distance formula:

d = $\sqrt{(x_{2}-x_{1})+(y_{2}-y_{1}) }$

Plug in variables:

d = $\sqrt{(0-(-6))+(0-(-7))}$

Simplify.

d = $\sqrt{6+7}$

d = $\sqrt{13}$

The distance between the two points is $\sqrt{13}$ units.

Hope this helps!

Answer:

A)3.125hr

B)53.325mi

Step-by-step explanation:

speed=distance/time

an hour and 15min=1.25hr

32/1.25=25.6mi/hr

80/25.6=3.125hr

2hr and 5min=2+5/60=2.083hr

2.083x25.6=53.325mile
