Question
2. For this series of 4 questions, a man sits in the chair which is pin-connected to the 10-m frame BC. Frame BC rotates counterclockwise. Your final goal is to determine the magnitude of the support force N exerted by the chair on the man at the instant 0 = 30°. But before that, you need to answer some other questions. Please pay attention: the numbers may change from problem to problem since they are randomized. 2) If at this instance he has a speed of 6.5 m/s, which is increasing at 0.4 m/s², determine the magnitude of his total acceleration in m/s². Your answer must include 2 places after the decimal point. Your Answer: Answer 10 m B

Expert Solution
Step 1

The centripetal acceleration is given by:

v2r

(6.5)210 = 42.2510 = 4.225

 

 

 

However since the speed is increasing by 0.4 m/s2 it means there is tangential acceleration too.
