The appropriate response is a Surface wave. It is a seismic wave that goes over the surface of the Earth rather than through it. Surface waves as a rule have bigger amplitudes and longer wavelengths than body waves, and they travel more gradually than body waves do. Adore waves and Rayleigh waves are sorts of surface waves.

   Net force = (mass) · (acceleration)

   = (69 kg) · (29 m/s²)

   = (69 · 29) · (kg·m/s²)

What is the acceleration of an object that goes from 45m/s to 10 m/s in 5 seconds?

kipiarov [429]

Answer:

$\boxed {\boxed {\sf a= -7 \ m/s^2}}$

Explanation:

Acceleration is the change in velocity over time.

$a= \frac {v_f-v_i}{t}$

The object accelerates <em>from</em> 45 meters per second <em>to </em>10 meters per second in 5 seconds. Therefore,

$v_f=10 \ m/s \\v_i= 45 \ m/s \\t= 5 \ s$

Substitute the values into the formula.

$a= \frac{ 10 \ m/s - 45 \ m/s}{5 \ s}$

Solve the numerator.

$a= \frac { -35 \ m/s}{5 \ s}$

Divide.

$a= -7 \ m/s/s$

$a= -7 \ m/s^2$

The acceleration of the object is -7 meters per square second. The acceleration is negative because the object's velocity decreases and the object slows down.
