The figure shows the position-time (x - t) graph of one-dimensional motion of a body of mass 0.4 kg . If the graph is a sawtooth wave with peaks at 2 m every 2 seconds, the magnitude of each impulse is:

Solution & Step-by-step Explanation

Impulse J = Δ p = m (v_{f} - v_{i}) .From the graph, for 0 < t < 2, velocity v_{1} = slope = \frac{2 - 0}{2} = 1 m/s .For 2 < t < 4, velocity v_{2} = slope = \frac{0 - 2}{2} = - 1 m/s .At t = 2 s, the change in velocity is Δ v = - 1 - (1) = - 2 m/s .Magnitude of impulse J = ∣ m Δ v ∣ = 0.4 \times 2 = 0.8 Ns .

Try it yourself before checking the explanation above.
