please clear hand writing as i am not familiar with most terms
2. A 100 g block is attached to a spring and undergoing simple harmonic motion. Its position as a function of time can be described by z(t) (10 cm) cos (10 rad/s t) a. What is the block's maximum speed and maximum acceleration? In Physics 221 we saw that we can often approach motion problems from different per spectives and arrive at the same answer For example, when dealing with masses on springs, we can think of things in terms of the relationship between kinematic quantities (position, velocity, acceleration) or in terms of energy b. Using the relationship between position and velocity, what is the position of the mass when it is moving at 60% of its maximum speed? C. energy, what is the position of the mass when it is moving at 60% of its maximum speed?Explanation / Answer
2 a) Vmax= WA =10*.01=1 m/s ,amplitude A=0.1 m
a max =A w2 = 0.1*100 = 10 m/s2
