Question

Трамвайнай вагон движется на повороте по закругления радиусом 40 м рассчитать скорость трамвая если центростремительное ускорение равно 0,4 м с

Answer 1

V=корень из a*r

V=корень из 16

V=4

Answer 2

Calculation of the Tram's Speed on a Curved Track

To calculate the speed of a tram on a curved track, we can use the formula for centripetal acceleration. The centripetal acceleration is given by the equation:

a = v^2 / r

Where: - a is the centripetal acceleration - v is the velocity of the tram - r is the radius of the curved track

In this case, we are given that the centripetal acceleration is 0.4 m/s^2 and the radius of the curved track is 40 m. We need to find the velocity of the tram.

Using the formula for centripetal acceleration, we can rearrange the equation to solve for velocity:

v = sqrt(a * r)

Substituting the given values, we have:

v = sqrt(0.4 * 40) = sqrt(16) = 4 m/s

Therefore, the speed of the tram on the curved track is 4 m/s.
