Answer:

Centripetal acceleration, 52.6 m/s²

Explanation:

It is given that,

A teacup on a spinning teacup ride takes 1.5 s to complete a revolution around the center of the platform.

Distance covered by the particle in circular path is, d=2\pi r

We have to find centripetal acceleration of the teacup, a_c=\dfrac{v^2}{r}

Where, v is the velocity v=\dfrac{2\pi r}{t}

a_c=\dfrac{4\pi^2 r}{t^2}

a_c=\dfrac{4\pi^2\times 3}{(1.5)^2}

a_c=52.6\ m/s^2

Hence, centripetal acceleration of the teacup if it is 3.0 m from the center of the ride is 52.6 m/s²

A turntable reaches an angular speed of "45 rev/min" in "4.10 s" after being turned on. What is its angular acceleration?
Marina86 [1]

Answer:

1.15 rad/s²

Explanation:

given,

angular speed of turntable = 45 rpm

                       =45\times \dfrac{2\pi}{60}

                       =4.71\ rad/s

time, t = 4.10 s

initial angular speed = 0 rad/s

angular acceleration.

\alpha = \dfrac{\omega_f-\omega_0}{t}

\alpha = \dfrac{4.71-0}{4.10}

\alpha = 1.15\ rad/s^2

Hence, the angular acceleration of the turntable is 1.15 rad/s²

What is the main difference between a maglev train and a normal train?
professor190 [17]
Regular trains follow train tracks and travel on rails; Maglev trains are Magnetically Levitated using powerful electromagnets, so that they actually hover slightly above the ground. This massively reduces friction and allows them to travel much faster (kind of like how a puck can go really far with only a little push on an air hockey table).

A car is moving at a constant speed of 14 m/s when the driver presses down on the gas pedal and accelerates for 14 s with an acc
Vinil7 [7]

acceleration of car is 1.8 m/s^2

time = 14 s

initial speed = 14 m/s

so the final speed is calculated by

v_f = v_i + at

v_f = 14 + 14 * 1.8

v_f = 39.2 m/s

so the total distance moved in this interval of time is

d = \frac{v_f + v_i}{2}* t

d = \frac{39.2 + 14}{2}* 14

d = 372.4 m

now the average speed is given as

v = \frac{d}{t}

v = \frac{372.4}{14}

v = 26.6 m/s

so the average speed will be 26.6 m/s
