A material point R moves in the horizontal plane of the equation: x=x(t) y=y(t) (x and y in cm- t in seconds) required:

[correctanswer]

A material point R moves in the horizontal plane of the equation:
x=x(t)
y=y(t)
(x and y in cm- t in seconds)
required:
The trajectory of the material point R;
Speed ​​and acceleration of the material point R for time t; Tangential acceleration, normal acceleration and curvature radius for time t.
x= x(t)
for x= 3t2 +2
y= y(t)
for y=-14t
time (t)=1/2 s
