Question

A small block slides along the inside of a hemispherical bowl of radius r = 41.4 cm. When the block is at an angle of θ = 62.3° above the lowest point, it is sliding down with a speed of v = 3.02 m/s and speeding up at a rate of 3.54 m/s2. Find the coefficient of kinetic friction between the block and the bowl.

So the correct answer was 0.193, can someone please go over this step-by-step, I don't think it's the right answer at all.
