What is Andrea’s displacement after 137s ? Given: vavg = 6.02 m/s ∆T= 137s Unknown: ∆x = ? ∆x = vavg∆T = (6.02 m/s)(137s)= 825m to the east Average Velocity Practice Problem A bus travels 280km south along a straight path with an average velocity of 88 km/h to the south. The bus stops for 24 min. Then, it travels 210 km south with an average velocity of 75 km/h to the south. What is the average velocity for the total trip? Average Acceleration Sample Problem A shuttle bus slows down with an average acceleration of -1.8 m/s2. How long does it take the bus to slow from 9.0 m/s to a complete stop? Displacement With Constant A racing carAcceleration reaches a speed of 42 m/s. It then begins a uniform negative acceleration, using its parachute and braking system, and comes to rest 5.5s later. Find the distance that the car travels during braking. Velocity and Displacement with Constant Acceleration A plane starting at rest at one end of a runway undergoes a uniform acceleration of 4.8 m/s2 for 15s before takeoff. What is its speed at takeoff? How long must the runway be for the plane to be able to take off?
