Answer
given,
mass of crate attached by cable A = 160 Kg
mass of crate attached by cable B = 73 Kg
acceleration of helicopter = 1.4 m/s²
tension in the cable when the move up
F = m (a + g)
tension in cable B
F = 73 x (1.4 + 9.8)
F = 73 x 11.2
F = 817.6 N
tension in cable A
F = (160 + 73 ) x (1.4 + 9.8)
F = 233 x 11.2
F = 2609.6 N
Before you step on the brakes, the car has kinetic energy, when you step on the brakes, it turns the kinetic energy into heat (thermal energy). When it stops completely, it has potential energy. Hope this helped :)
