Two particles P and Q are located at the origin of a co-ordinate system.Both the particle start moving simultaneously at time t=0 .Particle P moves with a constant speed of 2pi m/s on a circle x^(2)+y^(2)+120y=0 in clock wise direction while Q moves with a constant acceleration such that at t=5s velocities of both are same. Find :(a)The average acceleration of P during this time (b)the position vectors and velocities of particles at t=5s |
| Answer» Solution :(a)`(pi)/(5(-026hati)m//s^(2)`, (B) (30`HATI`-7.8`hatj`)m,13.65`hati`-7.85 `hatj`)m,`pi(1.74hati-hatj`)m/s | |
