Consider the 65.0-kg ice skater being pushed by two others shown in the figure below.

(b) What is her initial acceleration if she is initially stationary and wearing steel-bladed skates that point in the direction of Ftot? (Assume friction is negligible. Enter the magnitude only.)
m/s2
(c) What is her acceleration assuming she is already moving in the direction of Ftot? (Assume friction is negligible. Enter the magnitude only.)
