What is the tension in a rope accelerating a 1000 kg car upward at 0.80 m/s²?

Click For Summary
SUMMARY

The tension in a rope required to accelerate a 1000 kg car vertically upward at 0.80 m/s² is calculated by considering both the force of gravity and the additional force needed for acceleration. The gravitational force acting on the car is 9800 N (calculated using F = mg, where g = 9.8 m/s²). To find the total tension, one must add the force required for acceleration (800 N) to the gravitational force, resulting in a total tension of 10600 N in the rope.

PREREQUISITES
  • Understanding of Newton's Second Law (F = ma)

Homework Statement



How much tension must a rope withstand if it is used to accelerate a 1000 kg car vertically upward at 0.80 m/s2? Ignore Friction.

Homework Equations



fay= ma ?
mg-fn=0

The Attempt at a Solution



F=MA
F=1000kg * .8
F= 800 WRONG!

It says you're pulling against gravity as the car moves upwards. Means you have to have at least 9800 N just to hold the thing steady. 800 would be right if it was moving vertically.
 
so the question is asking how much tension the rope must endure to accelerate 1000kg at .8m/s/s. So would that mean 9800+800?
