A boat travels 12.0 m while it reduces its velocity from 9.5 m/s to 5.5 m/s. What is the magnitude of the boat’s acceleration while it travels the 12.0 m?

• 1.3 m/s²
• 2.5 m/s²
• 3.0 m/s²
• 7.5 m/s²

An object with an initial velocity of 3.50 m/s moves east along a straight and level path. The object then undergoes a constant acceleration of 1.80 m/s² east for a period of 5.00 s. How far does the object move while it is accelerating?

• 6.30 m
• 17.5 m
• 27.2 m
• 40.0 m
