Chapter 12.7, Problem 7PP

a. Determine the acceleration at the instant shown.

b. Determine the increase in speed and the normal component of acceleration at s = 2 m. At s = 0, v = 0.

c. Determine the acceleration at the instant shown. The particle has a constant speed of 2m/s.

d. Determine the normal and tangential components of acceleration at s = 0 if v = (4s + 1) m/s, where s is in meters.

e. Determine the acceleration at s =2 m if $\stackrel{\dot{}}{v}$ = (2 s) m/s², where s is in meters. At s = 0, v = 1 m/s.

f. Determine the acceleration when t = 1 s if v = (4t² + 2) m/s, where t is in seconds.
