Question

A marble rolls across the floor. Its initial velocity is 1.1 ft/s, but it has slowed to 0.81 ft/s by the time it has traveled 4 ft. Find the magnitude of the acceleration of the marble in ft/s2.

Answer 1

use the equations of motion\[V_f^2 = V_0^2 + 2*a* \Delta x\] and solve for acceleration
