Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The function in t is f(t)=5t³-4t²+2t+3 then the acceleration become zero at
A
4/15 sec
B
2 sec
C
1/15 sec
D
5/16sec
Explanation: 

Detailed explanation-1: -(a) The acceleration at t = 0 must be zero.

Detailed explanation-2: -acceleration at t=2s=4m/s2 (in direction of motion).

Detailed explanation-3: -The acceleration of the particle when t = 4 is 2 m/s2.

Detailed explanation-4: -Acceleration (a) is the change in velocity (v) over the change in time (t), represented by the equation a = v/t. This allows you to measure how fast velocity changes in meters per second squared (m/s^2).
