1. The disc radius of 10 cm rotates at a constant angular velocity. When braking, he began to spin slowed by the equation φ = 8t - 1,5t2, where φ - the angle of rotation in radians and t - time in seconds. Determine at time t = 2, starting from the beginning of braking, tangential, normal and full acceleration points on the circumference of the disc.
