Qu. 5 A particle is moving along a circular path having a radius of 4 in. such that its position as a function of time is given by 0 = cos 2t, where 0 is in radians and t is in seconds. Determine the magnitude of the acceleration of the particle when 0 = 30º. Qu. 6 A block moves outward along the slot in the platform with a speed of ŕ = (4t)m/s, where t is in seconds. The platform rotates at a constant rate of 6 rad/s. If the block starts from rest at the center, determine the magnitudes of its velocity and acceleration when t = 1 s. = 6 rad/s
