Final answer:

Using the principles of physics, particularly Newton's second law of motion, the time needed to move a 1330 kg car 5.00 m with a force of 187 N is approximately 33.5 seconds.

Step-by-step explanation:

This question wants us to find the time it will take for a 1330 kg car to move 5.00 m when pushed with a 187 N force. From Newton's second law of motion, we can establish the equation F=ma (Force equals mass times acceleration). We are able to calculate the acceleration by rearranging the equation as a=F/m (acceleration equals force divided by mass). This results in an acceleration of 187 N / 1330 kg = 0.14 m/s².

Next, we use the equation for distance d = 0.5 * a * t² (distance equals half the acceleration times the time squared). Rearranging the equation to solve for time gives t = sqrt(2d/a) (time equals the square root of twice the distance divided by acceleration). Substituting the given values, we find t = sqrt(2*5.00 m / 0.14 m/s²) = 33.5 seconds.

Therefore, it would take about 33.5 seconds to move the 1330 kg car 5.00 m with a force of 187 N.
