Question

A particle moves along the x-axis, its position is given by the equation: What is Its acceleration when it changes direction?

Answer 1

Answer:

Explanation: 2.1 A particle is moving along the x-axis. Its position is given by the equation: x = 2 + 3t – 4t2 where (x) is in meters and (t) is in seconds. Determine (a) its position when it changes direction and (b) its velocity when it returns to the position it had at t = 0. ... When the speed is zero2.1 A particle is moving along the x-axis.
