* 83% 8:42 AM quest.cns.utexas.edu TMobile LTE 020 10.0 points The motion of a piston in an auto engine is simple harmonic. The piston travels back and forth between the extreme points 30 cm apar e to 2083 rpm 30 cm What is the maximum speed of the pis- ton when the engine is running at 2083 rpm e to (revolution per minute)? Answer in units of m/s. 021 10.0 points When a body executes simple harmonic mo- tion, its period is tion- 1. proportional to its acceleration. 2. inversely proportional to its accelera- tion 3. proportional to its amplitude. 4. independent of its amplitude. 5. the reciprocal of its speed. A piston in an automobile engine is in simple 022 (part 1 of 2) 10.0 points

Explanation / Answer

amplitude = 0.3 m

rpm = 2083

angular velocity = 2083 x 2 x pi / 60 = 218.13

max velocity = aw = 65.43 m/sec
