An elevator car with a mass of 500 kg moves with an acceleration of 0.100 (m/s 2). With what force the cable

An elevator car with a mass of 500 kg moves with an acceleration of 0.100 (m/s 2). With what force the cable acts on the suspension of the car, if the elevator car: a) starts moving up b) stops, going down c) stops, going up d) starts moving down

given
lift car weight = 500 kg
acceleration a = 0.100 m / s squared.
find strength
a) find the force when the elevator moves up
P = m * (g + a) = 500 kg * (10 m / s squared + 0.1 m / s squared) = 500 * 10, 1 N = 5050 N;
b) find strength if the elevator stops going down
P = 0 + m * (g + a) = 500 kg * (10 m / s squared + 0.1 m / s squared) = 500 * 10, 1 N = 5050 N;
c) find strength if the elevator stops going up
P = m * (g – a) = 500 kg * (10 m / s squared – 0.1 m / s squared) = 500 * 9.9 N = 4950 N
d) find the force when the elevator moves down
P = 0 + m * (g – a) = 500 kg * (10 m / s squared – 0.1 m / s squared) = 500 * 9.9 N = 4950 N
