(3) A Ninja motorcycle is moving down I95 at 160 miles per hour (72 m/s) and a cop uses a radar gun to measure the speed. Using

the formula:
( λ’ -λo)/λo =v/c with a laboratory wavelength of 2.8 cm, can you answer whether of not the radar gun uses the doppler effect to directly measure speed from the motorcycle?

In a crash test, a 1000 kg automobile moving at 10 m/s crashes into a brick wall. How much energy goes into demolishing and warm
marishachu [46]

Answer:

Explanation:

Given

mass of automobile m=1000\ kg

velocity of automobile v=10\ m/s

If the automobile crashes into the brick wall then it's kinetic energy is converted into thermal and demolishing energy to wall.

Car completely stops as it crashes into the wall so Energy converted into demolition and thermal energy

E=\frac{1}{2}mv^2

E=\frac{1}{2}\times 1000\times (10)^2

E=50\ kJ

Haley is trying to pull an object upward. The below forces are acting on the object.
ra1l [238]

For this case, the first thing we must do is define a reference system.

Suppose that the positive direction of the reference system is upward.

We have that the sum of forces in the vertical axis is given by:

Fy = Fp - Fg

Substituting values:

Fy = 5500 - 6000

Fy = - 500

The negative sign means that the direction of the force with respect to the defined coordinate system is downward.

Answer:

The net force is:

↓ 500N
