Your concave plate with a mass of 2 kg is spinning on top the table with a velocity of 1.5

rad/s for 2 seconds then your brother came and spins it more creating a velocity of 4 rad/s

for 6 seconds. What is the angular acceleration of your concave when you are spinning it

and the angular acceleration after your brother spins it?

Expert's answer

"a_2=\\frac{v_2-v_1}{t_2}=\\frac{4-1.5}{6}=0.42\\frac{m}{s^2}"
