Solving for Tension in an Elevator with Acceleration of 3.0 m/s^2 | Physics Help

[Aiasha]

guys iam takin physics
its a takhom test
nd i don't get physics attt allll!
pllz hlp me with this
i need to show work as well

an elvtor weighing 25,000 N is supported by a steal cable. that is the tension in the cable wehn the elavotor is begin accelerated upward at the reate of 3.0 m/s^2? (g= 9.8m/s^2)
pleasezz help[

TIP: The tension in the cable must be greater than the gravity pulling down. Think about that.

Also remember that if this is an isolated system where only tension and gravity are acting on the elevator, the net force is equal to the gravity + tension. Is there a way you can find the mass? Once you find the mass, might there be also be a way to calculate the netforce using mass and the acceleration? REmember, Netforce=Gravity+Tension

remember

$$\sum \overline{F} = m\overline{a}$$

directions are imp.
