In 1.0 second, a particle goes from point A to point B moving in a semicircle (see figure). The magnitude of the A average velocity is
(a) 3.14 m/s
(b) 2.0 m/s
(c) 1.0 m/s
(d) Zero.
A particle initially is moving at a velocity with Cartesian components (5.0 m/s, 4.0 m/s) and 5.6 s later it is moving at a velocity with components (8.0 m/s, 0.0 m/s).
What is the magnitude of its average acceleration, in m/s2?
A particle travels along the x-axis such that its velocity is given by
v(t) = t sin (2t). If the position of the particle is x = -2 when t = 0, what is the
position of the particle when t = 6? You may use a calculator and round your answer
to the nearest thousandth.
