**Question 2:** A 2-kilogram ball is being dropped from a roof that is 15 meters off the ground. What is the final velocity of the ball?- \( d_y = \) ________- \( a = \) ________**Options:**- \( -294 \, \text{m/s} \)- \( -12.1 \, \text{m/s} \)- \( -1.53 \, \text{m/s} \)- \( -17.1 \, \text{m/s} \) *(Selected option)***Explanation:**In this problem, the aim is to find the final velocity of a ball dropped from a height using the known values of distance and acceleration due to gravity. The calculation involves using kinematic equations to solve for the final velocity. The selected answer is \(-17.1 \, \text{m/s}\).This is a basic physics problem demonstrating concepts of free fall and velocity.

2. In a scifi movie about astronauts on a space station, one of the astronaut's safety line is cut while on a space walk. The astronaut, who 10 meters from the shuttle and is moving 0.1 m/s away from it, finds that the suit's thruster pack has also been damaged and no longer works and that only 30 seconds of air remains. To get back to the shuttle, the astronaut unstraps a 10-kg tool kit and throws it away with a speed of 5 m/s. In the scene, the astronaut, who has a mass of 100 kg without the toolkit, survives. Is this reasonable?
