Please solve these 2 question in details. Thanks so much in advance.

1.3.3 From past midterm. The normal component of acceleration of a moving object in space at time t is given by (IN 2 327? If the radius of curvature at time t is p(t) = 2(t3 l 1)3/2, nd the tangential acceleration (IT at t=2. 1.3 .5 From past midterm: A frictionless highway has a constant curvature 1.96 X 10'2m'1. and is banked at an angle 6 = tan'1(0.2). What will be the maximum safe speed for the turn in m/s. You can take 9.8m/s'2 as gravitational acceleration
