Example 2: A caterpillar crawling up a leaf slows from 0.75 cm/s to 0.50 cm/s at a rate of -0.05 cm/s2 . How long does it take the caterpillar to make the change? Given: vi = 0.75 cm/s vf = 0.50 cm/s a = -0.05 cm/s2 Unknown: t = ? Original equation: 𝑎 = 𝑣𝑓−𝑣𝑖 𝑡 Solve: 𝑡 = 𝑣𝑓−𝑣𝑖 𝑎 = 0.50cm s ⁄ – 0.75cm s ⁄ −0.05 𝑐𝑚 𝑠 ⁄ 2 = 5 seconds
