How much tension must a cable withstand to accellerate a 1400 kg car vertically upward at 0.70 m/s^2
MariettaO [177]

Answer:

Below

Explanation:

The cars upward accel adds to the gravity accel (think about how suddenly heavy you feel when the elevator starts to move upward)

F = tension = ma

                   = 1400 * ( .7 + 9.81) = 14714 N
