Question
I know I have atleast one of my answers wrong, was hopeing you could take a look at the questions and give me your thoughts.
Explanation / Answer
it seems that your responses to following ARE RIGHT >> B) Greater than C) Greater than D) Equal to E) False ============= may consider the following a) less than bcause for acceleration at C > you need to consider one just forward point and just backward point v (forward) = v(final) = less than =v (backward) = v(initial) acceleration (along +x) = -ve = v(final - v(initial)/time or less than zero particle approaches (C) at top speed from left >>then speed falls as it rises ================ F) The velocity at A equals the velocity at B. (TRUE/FALSE) speed at A = speed B because both entail same altitude (PE) when PE's are same >> then KE's are same >> square of velocity in KE>> only clear sppeds being same ======== for v(A) = V(B) >> vectors > veocities tangents at A and B must also point in the same direction v(B)= |v| (i) unit vector in +x direction v(B)= |v| [(i) + j] >> [x,y] plane so F) is false
