arvind drops a scale vertically which is grabbed by Vijay whose hand is just below the scale. In the mean time the scale slips by 20cm. What is the reflex time of Vijay?
cristo said:Do you know any equations that may help you here? (hint: constant acceleration).
Is there a reason why this is in the tutorial forum? In future please post in the homework forum.
ritwik06 said:yes, the acceleration will be 9.8 m/sec^2. But how will this help?
oh! I am sorry once again. I haven't understood till now, as to which question should I post in which section. I am sorry again.
cristo said:Correct. Do you know any equations that will help you here? You are told the displacement, and you know that the initial velocity is zero.
That's ok. I'm sure it'll be moved for you soon anyway! In future though, use the homework forum. It's the second forum in the list on the front page (just under the tutorial forum)
cristo said:Have you come across the kinematic equations, for constant acceleration? Here's a link to them (scroll about half way down the page): http://www.glenbrook.k12.il.us/GBSSCI/PHYS/Class/1DKin/U1L6a.html . Which one do you think is most useful in this case?

Vijay's reflex time when Arvind drops a scale refers to the amount of time it takes for Vijay to respond and catch the scale after it is dropped by Arvind.
Measuring Vijay's reflex time when Arvind drops a scale can provide information about his reaction time and hand-eye coordination, which can be important in various activities and sports.
Vijay's reflex time when Arvind drops a scale can be measured by having Arvind drop a scale from a specific height and using a stopwatch to record the time it takes for Vijay to catch it.
Vijay's reflex time when Arvind drops a scale can be affected by various factors such as fatigue, distractions, and previous experience with catching objects.
Vijay can improve his reflex time when Arvind drops a scale by practicing catching objects of different sizes and weights, improving his hand-eye coordination through exercises and activities, and maintaining a healthy lifestyle to reduce fatigue.
