A) \[tan{{25}^{o}}\]to \[tan{{50}^{o}}\]
B) \[cos{{25}^{o}}\]to \[cos{{50}^{o}}\]
C) \[\tan {{25}^{o}}\] to \[\tan {{40}^{o}}\]
D) \[\sin {{25}^{o}}\] to \[\sin {{50}^{o}}\]
Correct Answer: A
Solution :
: As the slope of velocity-time graph gives acceleration, so acceleration \[a=\tan \theta \] \[\therefore \] From given graph, The acceleration of A is \[{{a}_{A}}=\tan {{25}^{o}}\] and that of B is \[{{a}_{B}}=\tan {{50}^{o}}\] Their corresponding ratio is \[\frac{{{a}_{A}}}{{{a}_{B}}}=\frac{\tan {{25}^{o}}}{\tan {{50}^{o}}}\]You need to login to perform this action.
