To investigate the effect of force orientation on the velocity of a collar, following experiment has been conducted. Force F is applied to the following collar to slide on a horizontal shaft. The coefficient of friction between the collar and shaft is µr. Although the magnitude of the force is constant (F < mg), its direction is variable. Velocity of collar when 0 = 0 is v, to the right. If 0 varies with time such that 0 kt, where k is a constant, determine velocity of the collar, v2, when O is 90°. Also, find magnitude of F in which vi=v2. F Fixed-magnitude force with variable direction m

To investigate the effect of force orientation on the velocity of a collar, following experiment has been conducted. Force F is applied to the following collar to slide on a horizontal shaft. The coefficient of friction between the collar and shaft is lk. Although the magnitude of the force is constant (F < mg), its direction is variable. Velocity of collar when 0 = 0 is v, to the right. If 0 varies with time such that 0 kt, where k is a constant, determine velocity of the collar, v2, when O is 90°. Also, find magnitude of F in which v1=v2. Fixed-magnitude force with variable direction m

What about v2 at theta = 90

To investigate the effect of force orientation on the velocity of a collar, following experiment has been conducted. Force F is applied to the following collar to slide on a horizontal shaft. The coefficient of friction between the collar and shaft is lk. Although the magnitude of the force is constant (F < mg), its direction is variable. Velocity of collar when 0 = 0 is v, to the right. If 0 varies with time such that 0 kt, where k is a constant, determine velocity of the collar, v2, when O is 90°. Also, find magnitude of F in which v1=v2. Fixed-magnitude force with variable direction m
