A skateboard rider starts from rest and accelerates at a constant 0.50m/s^2 for 8.4s. What is the rider's displacement during this time?
a=50
t=8.4
u=0
find s
formula [2] has these variables and no others so that is the one you need to use
$$\\s=ut+\frac{1}{2}at^2\\\\s=0+\frac{1}{2}*50*8.4^2\\$$
YOU CAN FINISH IT
