A mass of 5 kg slides across a frictionless table with an initial velocity of 10 m/s. The wind
starts to blow in the direction the mass is moving causing it to accelerate at a constant rate.
After 2 seconds, the mass is moving at a velocity of 15 m/s. What is the acceleration of the
mass?
A 12.5 m/s 2
B 7.5 m/s 2
C 5.0 m/s 2
D 2.5 m/s
