Figure 1 shows the velocity graph of a particle moving along the x-axis. Its initial position is x0 = 2.0 m at t0 = 0 s.
a) At t = 3.0 s, what is the particle's position?
b) At t = 3.0 s, what is the particle's velocity?
A particle moves in the xy plane with constant acceleration. Attime zero, the particle is at x = 10.0 m, y = 4.0 m, and hasvelocity v = 2.0 m/s + -4.0 m/s . The acceleration is given by thevector a = 8.0 m/s2 + 8 m/s2 .(a) Find the velocity vector at t = 7.0 s.( m/s)i + ( m/s) j(b) Find the position vector at t = 1.0 s.( m)i + ( m)j(c) Give the magnitude and direction of the position vector in part(b).m° (counterclockwise from the +x-axis)
A physics student on Planet Exidor throws a ball, and it followsthe parabolic trajectory shown in the figure below. The ball'sposition is shown at 1.0 s intervals until t = 3.0 s. Att = 1.0 s, the ball's velocity has componentsvx = 2 m/sand vy = 2m/s.
