1A 1500-kg elevator moves upward with constant speed through a vertical distance of 30 m. How much work was done by the tension in the elevator cable? a. 380 000 J A spring is attached to the ceiling of an elevator and a block of mass M is suspended from the spring. In Case A, the elevator moves up with a constant speed of 5 m/s. In Case B, the elevator moves downward with a constant speed of 10 m/s. Will the string . Calculus angle of elevation How to prove someone threatens youIntegrated Concepts An elevator filled with passengers has a mass of 1700 kg. (a) The elevator accelerates upward from rest at a rate of $1.20 \textrm{ m/s}^2$ for 1.50 s. Calculate the tension in the cable supporting the elevator. (b) The elevator continues upward at constant velocity for 8.50 s. What is the tension in the cable during this time? A car weighing 1400 kg is moving at a speed of 54 km/h up a hill when the motor stops. If it is just able to reach the destination which is at a height of 10 m above the point, calculate the work done against friction (negative of the work done by friction). Bassett living room ideas
