Question1-5

A truck travels due east for a distance of 1.7 km, turns around and goes due west for 6.6 km, and finally turns around again and travels 2.8 km due east. (a) What is the total distance that the truck travels? km (b) What are the magnitude and direction of the truck's displacement? magnitude km direction --Select-- v Supporting Materials Physical Constants Submit Answer -/2 Points] DETAILS OSCOLPHYS1 2.P.003.WA. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Two soccer players kick a soccer ball back and forth along a straight line. The first player kicks the ball 19 m to the right to the second player. The second player kicks the ball to the left weakly; it only moves 1.7 m before stopping. (Consider the right to be the positive direction. Where applicable, indicate the direction with the sign of your answer.) (a) What is the total distance that the ball moved? m (b) At the end, what is the displacement of the ball (from the first player)?

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A woman drives a car from one city to another with different constant speeds along the trip. She drives at a speed of 90.0 km/h for 20.0 min, 85.0 km/h for 15.0 min, makes a stop for 30.0 min, then continues at 45.0 km/h for 35.0 min, at which point she reaches her destination. (a) What is the total distance between her starting point and destination (in km)? km (b) What is the average speed for the entire trip (in units of km/h)? km/h Supporting Materials Physical Constants -/2 Points] DETAILS OSCOLPHYS1 2.P.009.WA. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A particle moves in one dimension, and its position as a function of time is given by x = (1.7 m/s)t + (-2.8 m/s2)t2 (a) What is the particle's average velocity from t = 0.45 s to t = 0.55 s? (Indicate the direction with the sign of your answer.) m/s (b) What is the particle's average velocity from t = 0.49 s to t = 0.51 s? (Indicate the direction with the sign of your answer.) m/s
