It takes off vertically with its rotor exerting a constant upward thrust of 112 kN. Use the principle of work and energy to determine how far it has risen when its velocity is 6 m/s. Strategy: Be sure to draw the free-body diagram of the helicopter. Solution: U12 = T2 − T1 (112000 − 93009.81)Nh = 1 (9300 kg)(6 m/s)2 2 h = 8.06 m. C 2008 Pearson Education South Asia Pte Ltd.

The coefficient of kinetic friction between the box and the surface is µk = 0.2. Determine how fast the box is moving when it has moved 2 m from its initial position (a) by applying Newton’s second law; (b) by applying the principle of work and energy.

15.11 where Y ≡ H2, Ym ≡ H2m, Ysp ≡ H2sp, D ≡ Q1, Dm ≡ Q1m, and U ≡ Q3. B) (A steady-state mass balance on both tanks gives 0 = q1 – q3 or Q1 = Q3 (in deviation variables) (1) From the block diagram, at steady state: Q3 = Kv Kf Kt Q1 From (1) and (2), Kf = 1 v tK K (2) c) (No, because Eq. 1 above does not involve q2. 15.4 (b) From the block diagram, exact feedforward compensation for Q1 would result when Q1 + Q2 = 0 Substituting Q2 = KV Gf Kt Q1, Gf = − 1 v tK K 15-3 (c) Same as part (b), because the feedforward loop does not have any dynamic elements.
