Estimated OAT Physics Score: Less than 200
Determine what knocked you down in the first round and get up and win the other rounds! You can do it and we have faith in you! In the famous words of Thomas Edison, “I have not failed. I’ve just found 10,000 ways that won’t work”. The only real mistake is the one from which we learn nothing. Get up, stand up, keep your head up and keep on fighting! We are monitoring you and watching your performance as you improve and have full confidence in you…

Question 1 of 9
1. Question
Stephen Curry, who weighs 60 kg, shoots a basketball, which weighs 0.5 kg, at a speed of 5 m/s. The total distance of his range of motion while shooting is 1 m. What force does Curry exert on this ball?
CorrectSolution:
We first need to find the acceleration using this formula:
(final velocity)2 – (initial velocity)2 = 2*acceleration*distance
We can deduce that initial velocity is 0.
After rearranging, we get:
a = vf2/(2s)
a = 52/(2*1)
a = 12.5 m/s2Then, we use the fundamental formula for force:
F = ma
F = (.5)(25)
F = 6.25 NWhy the other choices are wrong:
A, C) You get these two choices if you forget to divide by 2, either while calculating acceleration or while calculating force
D, E) You get these two choices if you factor in the weight of the player, which has no relevance to this problem

Question 2 of 9
2. Question
If the wavelength of a particular wave in water is doubled, how will this affect the velocity of the wave?
CorrectSolution:
The speed of a wave depends usually on the medium through which it travels, not wavelength or frequency
Why the other choices are wrong:
Light itself is free of the tangles of wavelength and frequency when it comes to speed. The only thing that matters is how dense the medium is.
