A small model car with mass m travels at a constant speed on the inside of a track that is a vertical circle radius 5.00 m. If the normal force exerted by the track on the car when it is at the bottom of the track (point A) is equal to 2.50 mg, how much time does it take the car to complete one revolution around the track?

Based on the information given, it can be deduced that the time taken will be 3.63 seconds to complete the revolution.

It should be noted that when the car is at the bottom, the formula to use from Newton's equation will be:

N - mg = (m × v²) / r

2.5 - 1 = v² / (g × 5)

1.5 = v² / (10 × 5)

1.5 = v² / 50

v² = 50 × 1.5

v = ✓75

v = 8.66m/s

Therefore, the time taken will be:

= (2 × pi × r) / v

= (2 × 3.142 × 5) / 8.66

= 3.63 seconds.

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
