Question

The motion of a particle along a straight line is
described by equation x = 2 + 12t - t2, where xis
in m and t is in s. The retardation of the particle
when its velocity becomes zero is
@ 2 m/s2
(2) 12 m/s2
(3) -2 m/s2
(4) -12 m/s2
2) 200​

Answer 1

Answer:

Explanation: The retardation of the particle when its velocity become zero is ... The particle's retardation is 12\ m/s^2. Given ... 12-3 t^{2}=0 \Rightarrow 12=3 t
