From the information in the question, the velocity of the particle is 24 ms-1.
Let us recall that the velocity of a body is obtained as the first derivative of distance covered with respect to time. Hence;
ds/dt = v
Now, we have to differentiate (t^3- 3t^2 + 2)m with respect to t and we have;
d(t^3- 3t^2 + 2)m/dt = 3t^2 - 6t
Now at t= 4s, the velocity of the particle is;
3(4)^2 - 6(4) = 24 m/s
The acceleration of the particle is the second derivative of distance with respect to time;
d^2s/dt^2 = d^2 3t^2 - 6t/dt^2 = 6t
Substituting t = 4s
a = 24 ms-2

Answer: Convection
Explantion: Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection
When the Skydiver jump out a plane, his Potential Energy is being converted or transform into Kinetic energy due to gravity. Hope this helps
Copper is widely sought world
market and New York mercantile exchange because of its very high thermal and
electrical conductivity. It is mostly used as a conductor of heat and
electricity, a component of various metals of alloy and as a building material.
