The mass of the car is 1633 kg.

<u>Explanation:</u>

Kinetic energy is the energy attained by the object when it is in motion. So the kinetic energy exhibited by any object is directly proportional to the mass of the object as well as the square of velocity of the object.

Thus as here the kinetic energy is given as 4.32 \times 10^{5} J and speed or velocity is given a 23 m/s, the mass (m) of the object can be found as

          \text {Kinetic Energy}=\frac{1}{2} \times \text { m } \times \text { speed }^{2}

         4.32 \times 10^{5}=\frac{1}{2} \times m \times 23 \times 23

Thus,

          \text {m}=\frac{4.32 \times 10^{5} \times 2}{23 \times 23} = 1633 \mathrm{kg}

How long must a tow truck apply a force of 600 N to increase the speed of a 1,500 kg car at rest to 2 m/s?
slega [8]

The time the truck must apply the given force to increase its speed to given value is 5 s.

The given parameters;

  • <em>applied force, F = 600 N</em>
  • <em>mass of the truck, m = 1,500 kg</em>
  • <em>speed of the truck, v = 2 m/s</em>

The force applied to the truck is determined by Newton's second law of motion; <em>which states that the force applied to an object is directly proportional to the product of mass and acceleration of the object.</em>

F = ma

F = \frac{mv}{t} \\\\t = \frac{mv}{F} \\\\t = \frac{1500 \times 2}{600} \\\\t = 5 \ s

Thus, the time the truck must apply the given force to increase its speed to given value is 5 s.

PLS HELP<br><br> compare longitudinal and transverse waves
babymother [125]
<span>A transverse wave is one for which the direction of oscillation is perpendicular to the direction of propagation of the wave whereas, for longitudinalwaves oscillations are in the direction of propagation. Ripples in pond water move about the surface of water and they simultaneously move away from the point-0 too.</span><span>
Longitudinal waves include sound waves(vibrations in pressure, particle of displacement, and particle velocity propagated in an elastic medium) and seismic P-waves (created by earthquakes and explosions). In longitudinal waves, the displacement of the medium is parallel to the propagation of thewave.
