Question

S=(6t²-2t)m at 3sec and 4sec​

Answer 1

Explanation:

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies

Answer 2

Answer:

pls mark me brainliest answer

Explanation:

Solution

s=t3−6t2+3t=4

v=dtds=3t2−12t+3

a=dtdv=6t−12

So, acceleration will be zero at

6t−12=0

t=2sec

Then velocity at t = 3

v=3(2)2−12(2)+3

    = 12-24+3

v=−9m/s
