Question

At t = 10 s, a particle is moving from left to right with a speed of 5.0 m/s. At t = 20 s, the particle is moving right to left with a speed of 8.0 m/s. Assuming the particle’s acceleration is constant, determine (a) its acceleration, (b) its initial velocity, and (c) the instant when its velocity is zero.

Step 1

Given: Initial velocity, \(v_1 = 5.0 \, \text{m/s}\) Final velocity, \(v_2 = -8.0 \, \text{m/s}\) Initial time, \(t_1 = 10 \, \text{s}\) Final time, \(t_2 = 20 \, \text{s}\) Acceleration, \(a = \frac{v_2 - v_1}{t_2 - t_1}\) Acceleration, \(a = \frac{-8.0 \, Show more…
