How would you calculate the speed (in #m/s#) of a skateboarder who accelerates from rest for 4 seconds down a ramp at an acceleration of #3 m/s^2#?

Applicable kinematic expression is
#v=u+at#
Inserting given values we get
#v=0+3xx4#
#v=12\ ms^-1#

Explanation:
Using the basic kinematics equation,
#u# is the initial speed
#a# is the acceleration
#t# is the time
And so,
