Explain how energy is transferred in an impact situation such as a car crash.

1 answer:

8 0

During a car crash, energy is transferred from the vehicle to whatever it hits, be it another vehicle or a stationary object. ... The object that was struck will either absorb the energy thrust upon it or possibly transfer that energy back to the vehicle that struck it.

One end of a string 4.32 m long is moved up and down with simple harmonic motion at a frequency of 75 Hz . The waves reach the o

max2010maxim [7]

To solve this problem, we will apply the concepts related to the kinematic equations of linear motion, which define speed as the distance traveled per unit of time. Subsequently, the wavelength is defined as the speed of a body at the rate of change of its frequency. Our values are given as,

$\text{Length of the string} = L = 4.32 m$

$\text{Frequency of the wave} = f = 75 Hz$

$\text{Time taken to reach the other end} = t = 0.5 s$

Velocity of the wave,

$V = \frac{L}{t}$

$V = \frac{4.32 m}{0.5s}$

$V = 8.64m/s$

Wavelength of the wave,

$\lambda = \frac{V}{f}$

$\lambda = \frac{8.64m/s}{75Hz}$

$\lambda = 0.1152m$

$\lambda = 11.52cm$

Therefore the wavelength of the waves on the string is 11.53 cm

Newton’s first law says that if motion changes, then a force is exerted. Describe a collision in terms of the forces exerted on

ira [324]

Answer:

In collision between equal-mass objects, each object experiences the same acceleration, because of equal force exerted on both objects.

Explanation:

In a collision two objects, there is a force exerted on both objects that causes an acceleration of both objects. These forces that act on both objects are equal in magnitude and opposite in direction.

Thus, in collision between equal-mass objects, each object experiences the same acceleration, because of equal force exerted on both objects.
