2024PPp1q6 Ball falling with inital velocity greater than terminal velocityEvan Toh16 hours ago1 min readUpdated: 23 minutes agoInstead of the usual ball release from rest, this question states that the ball has an initial velocity greater than terminal velocity in the air. There are a few scenarios which are possible.object moving in vacuum at high speed entering air (e.g. meteor entering Earth's atmosphere)object is thrown down from a high altitude at high speedparachute is opened and the speed decreases till terminal velocitystone falling with high speed in air hits the water and speed decreasesetcView the video for the explanation.Question: 2024PPp1q6Answer: Option A
