Ok so i want you to look at the formulas for velocity: v=vi(i=initial not a variable) + at x = xi + vit + 1/2at^2 v^2 = vi^2 +2aΔx Now circular motion formulas use the same variables only written differently: (ω=angular velocity)similar to v (α=angular acceleration)similar to a...

I showed that answer to my physics teacher and he says the answer is BOTH (a) and (b) and it just depends on what you perceive what happends after. If it bounces back the answer is 87N, however, if you thought like the way I did where it breaks through (since it is not specified in the question...

@ Vorde No i do not know the correct answer @SammyS I also don't know but i would assume that it is around 9.8m/s^2 I already attempted this question and i don't mind getting confused a bit since i have more help than just the website (actually people help).

Question 1 (All basic physics). A crane drops a 0.3 kg steel ball onto a steel plate. The ball's speeds just before impact and after are 4.5 m/s and 4.2 m/s, respectively.If the ball is in contact with the plate for 0.03 s, what is the magnitude of the average force that the ball exerts on the...
