Consider a horizontal floor without friction. Then a person of weight 900N pushes horizontally with a force of 200 N on a crate weighing 1800 N. Which statement could be true as a result of this push?
a. The crate will not move because the push is less than its weight.
b. The person will accelerate at 1.08 m/s^2 and the crate will accelerate at 2.17 m/s^2, but in opposite directions.
c. The person and crate will both have an acceleration of 1.08 m/s^2, but in opposite directions.
d. The person and crate will both have an acceleration of 2.17 m/s^2, but in opposite directions.
e. The person will accelerate at 2.17 m/s2 and the crate will accelerate at 1.08 m/s^2, but in opposite directions.
