7 0

Given that,

Radius of track, r = 50 m

time , t = 9 s

velocity, v = ?

Distance covered by car in one lap around a track is equal to the circumference of the track.

C = 2 π r = 2 * 3.14 * 50

C = 314.159 m

Distance covered by car, s = 314.159 m

Velocity = distance/ time

V = 314.159 / 9

V = 34.9 m/s

The average velocity of car is 34.9 m/s.

KiRa [710]

Answer:

0.11m/s

Explanation:

To solve the exercise it is necessary to apply the concepts related to the conservation of both: kinetic and spring energy(Elastic potential energy), in this way

Kinetic Energy = Elastic potential energy

KE = SE

\frac{1}{2}mv^2 = \frac{1}{2}kX^2

Where,

m=mass

v=velocity

k=spring constant

x=amount of compression

Re-arrange the equation to find the velocity we have,

v^2 = \frac{kX^2}{m}

v^2 = \frac{10(0.25)^2}{50}

v = \sqrt{0.0125}

v = 0.11m/s

Therefore the maximum speed of the bananas is 0.11m/s

kherson [118]

Answer:

Acceleration, a = 750m/s²

Explanation:

Given the following data;

Radius, r = 0.31m

Velocity, v = 15m/s

To find the centripetal acceleration;

Acceleration, a = \frac {v^{2}}{r}

Substituting into the equation, we have;

Acceleration, a = \frac {15^{2}}{0.31}

Acceleration, a = \frac {225}{0.31}

Acceleration, a = 750m/s²

Therefore, the centripetal acceleration of the bike wheel is 750m/s².
