The motion of a particle is given by the equation v = 8t3 – ½ t2 + 4t, where v is in meters and t is in seconds. Compute the val

ue of a at t=0. I got 98 m/s^2 but the answer key says 50m/s^2 so I think it must have been a typo. Can someone please check?

Answer:

4 m/s²

Explanation:

v(t) = 8t³ – ½ t² + 4t

Acceleration is the first derivative of velocity with respect to time.

a = dv/dt

a = 24t² – t + 4

At t = 0, the acceleration is:

a = 4

The process by which two or more tiny nuclei unite to generate a bigger nucleus is known as a nuclear fusion reaction. Heavier atoms are products of a fusion reaction.

<h3 /><h3>What is nuclear fusion?</h3>

The process by which two or more tiny nuclei unite to generate a bigger nucleus is known as a nuclear fusion reaction.

For example, the fusion of two hydrogen atoms produces more energy than the fusion of one helium atom, and surplus energy is expelled into space upon binding.

Hence heavier atoms are e products of a fusion reaction.

To learn more about nuclear fusion refer to the link;
