devlian [24]

Answer:

Kinetic energy = 0.45 joules

Explanation:

We have velocity of the particle is

$v=\frac{dx(t)}{dt}\\\\v=\frac{d(3t)}{dt}\\v=3m/s$

Now kinetic energy(K.E) is given by

$K.E=\frac{1}{2}mv^{2}$

applying values we get

Kinetic energy = $\frac{1}{2}0.1\times 3^{2}\\\\\therefore K.E=0.45Joules$

To prevent cars from falling, the radius at the top of the circle should be

small such cars inverted at the top remain attached during motion.

Correct response;

The radius of the coaster can be <u>C) 20 m</u>

<h3>Method by which the above option is selected</h3>

Mass of roller coaster car, m = 500 kg

Speed at the top of the circle, v = 20 m/s
