Im having trouble with a part of a problem. The problem is: There is an elevator with a mass of 1200[tex]kg[/tex] accelrating upward at 2.1[tex]m/s^2[/tex]. Find T. For that what I did was [tex]1200 \times 9.8m/s^2[/tex] which gave me 11,760. I then plugged this into [tex]F=ma[/tex] and got 14,280. The second part of the equation says: The elevator now moves with a constant upward velocity of 10[tex]m/s[/tex]. Find T. This is where I get stuck. I dont know how to factor in velocity.
