Since velocity describes both speed and direction you can call it

Physics
1 answer:
Fittoniya [83]3 years ago
4 0

Since velocity describes both speed and direction, you can call it a "vector" quantity, and legitimately label it "velocity".

Since speed has no direction, it's a scalar quantity, and it's wrong to call it "velocity" as so many often do.

During the launch from a board, a diver's angular speed about her center of mass changes from zero to 8.10 rad/s in 240 ms. Her
Artemon [7]

Answer:

Part a)

\alpha = 33.75 rad/s^2

Part b)

\tau = 391.5 Nm

Explanation:

Part a)

Average angular acceleration is given as rate of change in angular speed

so it is given as

\alpha = \frac{\omega_f - \omega_i}{\Delta t}

\alpha = \frac{8.10 - 0}{240\times 10^{-3}}

\alpha = 33.75 rad/s^2

Part b)

average external torque is given as

\tau = I\alpha

here we know that

I = 11.6 kg m^2

\tau = 11.6 \times 33.75

\tau = 391.5 Nm
