Question # 1: A motorist drives south at 20.0 m/s for 3.00 min, then turns west and travels at 25.0 m/s for 2.00 min, and finally travels northwest at 30.0 m/s for 1.00 min. For this 6.00-min trip, if the positive x-axis points east, find: a) the total vector displacement b) the average speed c) the average velocity Question # 2: A particle initially located at the origin has an acceleration of 3.00j m/s² and an initial velocity of 5.00i m/s. Find: a) the vector position of the particle at any time b) the velocity of the particle at any time c) the coordinates of the particle at t = 2.00 s d) the speed of the particle at t = 2.00 s Question # 3: Two forces, (-6i-4j) N and (-3i+7j) N, act on a particle of mass 2.00 kg that is initially at rest at coordinates (22.00 m, 14.00 m). a) What are the components of the particle's velocity at t = 10.0 s? b) In what direction is the particle moving at t = 10.0 s? c) What displacement does the particle undergo during the first 10.0 s? d) What are the coordinates of the particle at t = 10.0 s?
