A trolley accelerates uniformly from 6.0 m/s to 10 m/s over a distance of 16 m.
Use the equation v2−u2=2axv^2-u^2=2axv2−u2=2ax.
What is the acceleration of the trolley?
2.0 m/s22.0\ \mathrm{m/s^2}2.0 m/s2
0.50 m/s20.50\ \mathrm{m/s^2}0.50 m/s2
3.1 m/s23.1\ \mathrm{m/s^2}3.1 m/s2
4.0 m/s24.0\ \mathrm{m/s^2}4.0 m/s2
