Physics 141 Chapter 2 Worksheet (Due Wed 5/11, Noon) Name: Box#: 1. Write down the equation of motion for an object moving with constant velocity. (p. 18) Ax= 2. Write down the 4 equations of motion for an object moving with constant acceleration. (p. 45, 46) (p. 55) 3. a) What is the instantaneous acceleration at t=15? (use slope) a(1) _m/s? b) What is the acceleration att = 3.55? a(3.5) - WINI R$ Probs 4 -8: Identify which equation you would use to solve the following problems (don't solve): 4. A child slides down a hill on a toboggan with an acceleration of 15 m/s? If she starts at rest, how far has she traveled in 1.0 s? 5. A meteorite strikes a car leaving a dent 22 cm deep in the trunk. If the meteorite struck the car with a speed of 550 m/s, what was the magnitude of its deceleration, assuming t to be constant? 6. When you see a traffic light turn red you apply the brakes until you come to a stop. If your initial speed was 12 m/s, and you were heading due west, what was your average velocity during braking? 7. A rocket blasts off and moves straight upward from the launch pad with constant acceleration. After 3.0 s the rocket is at a height of 80 m. What is the magnitude of the rocket's acceleration?
