Instead it reverses direction and ends down on the ground below the window. Since the brick didn't break the glass, we know: О The force of the brick on the glass > the force of the glass on the brick. О The force of the brick on the glass the force of the glass on the brick. = О The force of the brick on the glass < the force of the glass on the brick. О The brick didn't slow down as it broke the glass.arrow_forwardAlexandra (wearing rubber boots for traction) is attempting to drag her 32.6-kg Golden Retriever across the smooth ice by applying a horizontal force.

Review the data from the lab and determine whether your data is within standard deviations. Report, using numerical values, whether your data for each angle is within standard deviations. An acceptable margin of error typically falls between 4% and 8% at the 95% confidence level. Review your data for each angle to determine whether the margin of error is within an acceptable range.
