The document presents a physics problem involving projectile motion, where a dart is thrown horizontally at 20 m/s and hits a target 0.1 seconds later, resulting in a distance of 2 meters. It also discusses the velocity of an object thrown vertically, indicating that it decreases over time due to gravity, confirming option (d) as correct. The solutions to both scenarios are provided with explanations based on the principles of motion and velocity calculations.

I need only the right choice 1- A dart is thrown horizontally toward X.docx
- 1. I need only the right choice 1. A dart is thrown horizontally toward X at 20 m/s as shown. It hits Y O.1 s later.The distance XY is A. 2 m B. 0.05m C. 0.1 m D. 0.5 m E. 1 m 2. An object is thrown vertically into the air. Which of the following graphs repro the velocity of the object as a function of time? rv B. I C. IV E. V Solution 1. option (a) is right. Velocity= distance/time Herw X= velocity Y= time XY= distance so that distance XY= 20m/s*0.1s= 2m >>>>>>>>>>> 2. Option (D) is right Velocity of object will decrease with time due to gravity This object will follow the equation v= u- gt
