The Answer of The position of a particle along the x axis is given by $x ( t ) = 5 t + 3 t ^ { 2 }$ , where t is in seconds and x(t) is in meters. The velocity of the particle at time t = 5 seconds is
A) 55 m/s.
B) 48 m/s.
C) 62 m/s.
D) 35 m/s.

The Position of a Particle Along the X Axis Is x(t)=5t+3t2x ( t ) = 5 t + 3 t ^ { 2 }x(t)=5t+3t2

The Position of a Particle Along the X Axis Is $x ( t ) = 5 t + 3 t ^ { 2 }$
