Question
A particle starting from rest moves with the acceleration 𝑎̅ = 4𝑡𝑖̂ - 3𝑡2𝑗 - 6𝑘̂ m/s2. Determine
the principal radius of curvature of its path at t = 1.5*041 sec
13.In a certain plane motion, it is known that when the radial distance from a fixed origin is r
= 2*041cm, the r – θ components of velocity are Vr = 9*041 cm/s and Vθ = 100*041cm/s,
while the
components of acceleration are ar = - 150 cm/s2 and aθ = 250 cm/s2. At this instant, find
the angular acceleration α (i.e, θ
̈) of the positive vector and the component of acceleration
normal to the path.
14. At the position shown in the figure, the block B is sliding outward along the straight rod
with the given values of velocity and acceleration relative to the rod simultaneously, the rod
has the given values of angular velocity ω and angular acceleration α.
Find the total acceleration of the block. What is the component of this acceleration normal
to the path described by the block?
angular velocity ω
angular acceleration α

It seems that the information for questions 13 and 14 is incomplete as there is no figure provided for question 14 and the angular velocity and acceleration values are missing. Please provide more information or clarify the given data for a more accurate solution.
