At the airport, you drag your 17.1 kg suitcase across the floor at a constant velocity using a strap that is at an angle of 47.1o above the horizontal. If the coefficient of kinetic friction between the suitcase and the floor is 0.352, what is the tension in the strap? How much work does the force of kinetic friction do on suitcase if you drag it 20 m? TENSION IN THE STRAP IS 62.9, PLEASE HELP SOLVE FOR WORK.

1. You walk up a staircase from floor 5 to floor 6 at constant velocity. Each floor is 4 m above the other. Your mass is 70 kg. a) How much WORK do you do? b) Does it depend on how steep the stairs are, that is, is it different if there are more steps each of which is less high? c) What if you slide your shoes along the steps dramatically increasing your friction, how does that change the...

M A mass M-1.2 kg is released from rest. From the initial height of 75 cm above the ground, the mass drops from an free spring (neither compressed, nor extended) of constant k = 590 N/m. The maximum compression of the spring, due to the impact of the dropping mass is sh = 160 mm. Analyse the system with respect to the balance of energy, and the apply the conservation of energy, considering the ground level as reference of the...

4. Travelling Waves and Their Characteristics A rope wave travels in the positive x -direction. You are also told that the speed of the wave is 1000 cm/s, its frequency is 200 Hz, and that the wave is subject to the following initial conditions: at x 0 and t = 0: y =-1 cm, and, at x = 0 and t : ar = +20 cm/s (this is the velocity of the point on the rope at horizontal...
