Question

What was the vertical component of her acceleration during push-off? the positive direction is upward?

Answer 1

The vertical component of her acceleration during push-off, when the positive direction is upward, is -9.8 m/s².

Step-by-step explanation:

The vertical component of her acceleration during push-off, when the positive direction is upward, is -9.8 m/s². In physics, the acceleration due to gravity is typically denoted by -9.8 m/s² when taken in the upward direction.

Answer 2

The answer of these two problems are : A) a = (F-W)/m = (100-500)/500/g = 9.8*500/500 = +9.8 m/sec^2 B) a1 = +9.8-g = 0
