Rocket Sled Example In Class 3.1 The sled starts from rest and accelerates at: a= -0.003 v 2 m/s 2 Until its velocity decreases to 100 m/s. a= 30 + 2t m/s 2 Until it reaches a velocity of 400 m/s. Then it hits a water brake and its acceleration is: a) What total distance did the sled travel? b) What is the sled’s total time of travel? Solution: What general relationship will you use? Problem Type: Find : Given :

Unformatted text preview: impact characteristics of materials. The projectile shown starts at s= 1.5 m and accelerates until it reaches the end of the barrel at s= 3.0 m . The acceleration can be modeled as: γ s c a = Where γ = 1.4 is the ratio of specific heats for air. Find the constant c necessary for the projectile to leave the barrel with a velocity of 200 m/s . Solution: What general relationship will you use? Problem Type: Find : Given :...
