Question

Problem (Impulse) • A body with initial velocity (2.0i - 7.0j)m/s is given an impulse causing its velocity to change to (-8.0i +1.0j) m/s. The mass of the body is 0.50 kg. If the duration of the impulse is 0.20 seconds, calculate the : a) constant force in unit vector notation. b) Magnitude of the constant force. c) Angle

Step 1

The change in velocity is given by the final velocity minus the initial velocity: Δv = (-8.0i + 1.0j) - (2.0i - 7.0j) = -8.0i + 1.0j - 2.0i + 7.0j = -6.0i + 8.0j m/s Show more…
