(II) At t = 0, a particle starts from rest at 𝓍 = 0 , y = 0 and moves in the xy plane with an acceleration a (→ above a) = (4.0 î + 3.0 ĵ ) m/s². Determine(b) the speed of the particle as a function of time,
exercise:1. a particle moving along x axis starts from x0 with initial velocity v0. its acceleration can be expressed in
4 A particle P moves on a straight line, starting from rest at a point O of the line. The time after P starts to move is ts, and the particle moves along the line with constant accelerationms2 until it passes through a point A at time t = 8. After passing through A the velocity...
4 A particle starts from rest at a point X and moves in a straight line until, 60 seconds later, it reaches a point Y. At time ts after leaving X, the acceleration of the particle is0.75 m s-2 for 0t4,0m s-2 for 4t54,-0.5 m s-2 for 54t 60.(i) Find the velocity of ...
We are interested in computing the so-called occupancy probability P(t,xx) that a particle (here, a Ca2+ ion), started from a fixed point xx at time 0, is at the bound state on the sensor at a later time t. Due to the sensor kinetics, the particle can undergo numerous binding/un...
