**Physics Problem: Calculating Average Force During Collision****Problem Statement:** During a snowball fight, a 0.30-kilogram snowball traveling at a speed of 17.0 m/s hits a student in the back of the head. If the contact time is 0.10 s, what is the magnitude of the average force on the student’s head? **Answer Box:** \[ \_\_\_\_\_\_ \text{ N} \] **Explanation:**In this problem, you are asked to calculate the magnitude of the average force exerted on the student's head by the snowball during the collision.To solve this problem, you can use the concept of impulse and momentum. The change in momentum (impulse) is equal to the force exerted multiplied by the contact time.The formula to use is:\[ \text{Force} (F) = \frac{\Delta p}{\Delta t} \]Where:- \(\Delta p\) is the change in momentum (mass \(\times\) change in velocity),- \(\Delta t\) is the contact time.First, calculate the change in momentum \(\Delta p\):\[ \Delta p = \text{mass} \times \text{change in velocity} = 0.30 \, \text{kg} \times 17.0 \, \text{m/s} = 5.1 \, \text{kg} \cdot \text{m/s} \]Next, plug the values into the formula:\[ F = \frac{5.1 \, \text{kg} \cdot \text{m/s}}{0.10 \, \text{s}} = 51 \, \text{N} \]So, the magnitude of the average force on the student’s head is \(\boxed{51 \, \text{N}}\).

A 70 kg space voyager is stranded on a 700 kg escape pod that has left the main spacecraft and is floating in free space (you may assume its velocity is 0 m/s). A rescue ship is approaching and will pass within 100 m of the escape pod. The space voyager plans to push herself away from the escape pod towards the point by which the rescue ship will pass (point P in the diagram). The space voyager knows that she can apply a constant force of 100 N while she pushes for the 0.50 s it takes her to straighten her arms. (a) What will her velocity be after she has finished pushing against the rescue pod? (b) How long before the rescue ship is due to arrive a point P should the space voyager begin her push?
