Problem 45P

A small toy airplane is flying in the ?xy?-plane parallel to the ground. In the time interval ?t = 0 to ?t? = 1.00 s, its velocity as a function of time is given by = (1.20 m/s2)?tî? + [ 12.0 m/s ? (2.00 m/s2)?t?]?j?. At what value of ?t? is the velocity of the plane perpendicular to its acceleration?

Step 1 of 3

Actin and Myosin II – Muscle Power Myosin II o Short lever arm with 2 light chains Myosin V o Long lever arm with 6 light chains Myosin’s power stroke – head takes 1 step o Use the energy of ATP to crank up the lever arm  Bind to actin filament  Release and take a step o Every step uses the energy of 1 ATP o The head domain is...
