Your engineering firm is asked to specify the maximum load for theelevators in a new building. Each elevator has a mass 490 kg when empty and maximumacceleration 2.24 m/s2. The elevator cables can withstand a maximum tension of 19.5 kN beforebreaking. For safety, you need to ensure that the tension never exceeds two-thirds of that value.What is the maximum load that the elevator can safely carry? How many70-kg people is that?Briefly but clearly explain the reasoning for your choice of the sign of the acceleration.
