Initially, a bicycle is at the position 7 = (130 m)i + (210 m)j. After 120 s, the position of the particle is 7 = (110 m)i + (240 m)j . What is the average velocity vector of the bicycle in that time
||
tinterval?
O Tav = (0.17 m/s)i + (-0.25 m/s)j
O Jay = (0.25 m/s)i + (-0.17 m/s)
O Tay = (-0.25 m/s)î + (0.17 m/s)
O Jay = (-0.17 m/s)i + (0.25 m/s)j
The velocity of a particle is V and is constant. It moves counterclockwise on a circle with center "O" and radius R.
Draw the circle. When the particle is in the vector R position, draw vector R, vector V, vector A, and vector da/dt(time derivative of acceleration).
