Physics
1 answer:
deff fn [24]3 years ago
5 0

Answer:

Travelled 18 km, they are 6 km from home.

Explanation:

12/2 (halfway) is 6km. So, 6 + 12 would be 18 km, total amount travelled. The total distance of the trip would be 24 km (12 km out, 12km back) if they travelled 12+6 (18km) then they only have 6 km more to go.

Determine the moment of inertia of a 14.8 kg sphere of radius 0.752 m when the axis of rotation is through its center.
vfiekz [6]

Answer:

I=3.348Kgm^2

Explanation:

From the question we are told that:

Mass m=14.8kg

Radiusr=0.752m

Generally the equation for inertia is mathematically given by

I=\frac{2}{5}mR^2

I=\frac{2}{5}14.8*(0.752)^2

I=3.348Kgm^2

How much work is done when you push a crate horizontally with 150 N across a 13-m floor
Mila [183]
Work = (force) x (distance)

When a force of 150 N pushes through a distance of 13 meters,
it does

             Work = (150 N) x (13 m) = 1,950 joules .

An airplane travels 80 m/s as it makes a horizontal circular turn which has a 0.80-km radius. What is the magnitude of the resul
Nadya [2.5K]

Answer: 600N

Explanation:

Centripetal force is the force that causes a body to move in a circular path.

Centripetal force = MV²/r

M = 75kg v = 80m/s r = 0.80km = 800m

Substituting the values given in the formula;

F = 75 × 80²/800

F = 600N

The magnitude of the resultant force on the 75kg pilot is 600N.
