How do i answer this:

a point on a rotating turntable 20.0 cm from the center accelerates from rest to a final speed of 0.700 m/s in 1.75 s. at t = 1.25 s, find the magnitude and direction of (a) the radial acceleration, (b) the tangential acceleration,
and (c) the total acceleration of the point.

Part a)

Part b)

Part c)

Explanation:

initial speed of the turn table at t = 0 is given as

after t = 1.75 s the speed is given as

now the tangential acceleration is given as

Part a)

Now the speed of the disc after t = 1.25 s is given as

here we will have

now radial acceleration is given as

Part b)

tangential acceleration is given as

Part c)

total acceleration is given as

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
