Car mass of 1167 kg accelerates on a flat highway from 10.0 m/s to 28.0 m/s. how much work does thr car's engine do on the car ?
jolli1 [7]
For the work-energy theorem, the work done by the engine on the car is equal to the variation of kinetic energy of the car:
W= K_f-K_i=\frac{1}{2}mv_f^2 -  \frac{1}{2} mv_i^2
where m=1167 kg is the mass of the car, v_i=10.0 m/s is the initial speed and v_f=28.0 m/s is the final speed.

Putting numbers into the equation, we find:
W= \frac{1}{2}(1176 kg)(28.0m/s)^2- \frac{1}{2}(1167 kg)(10.0 m/s)^2=4.0 \cdot 10^5 J

10 A particle in circular motion performs 30 oscillations in 6<br> seconds. Its angular velocity is?
Snezhnost [94]

Explanation:

Let omega = angular velocity (in rad/s). Then

omega = (# of oscillations)/(6 s)

= (30 osc)/(6 s) = 5 osc/s

We need to convert this to rad/s:

omega = (5 osc/s)(2π rad/osc)

= 10π rad/s

= 31.4 rad/s

How are the 1st and 2nd Laws of Motion connected?
yuradex [85]

Answer:

Newton's First Law states that an object with no net force acting on it remains at rest or moves with constant velocity in a straight line. Newton's Second Law states that the acceleration of an object is directly proportional to the net force on the object and inversely proportional to the mass of the object.
