WebThe original equation describing movement on a line was. s (t) = t³ - 6t² +9t. In this case, there were two times when the particle was speeding up. That would be where the velocity and acceleration are both positive OR both negative in sign. t (1, 2) Time between 1 and 2 seconds. t (3, ∞) Time greater than 3 seconds. WebClick here👆to get an answer to your question ️ 25. At time t = 0. a particle is at (2m, 4m). It starts moving towards positive x-axis with constant acceleration 2 m/s (initial velocity = 0). After 2 s, an additional acceleration of 4 m/s starts acting on the particle in negative y-direction also. Find after next 2 s. (a) velocity and (b) coordinates of particle. WebThis sign is reasonable because the train initially has a positive velocity in this problem, and a negative acceleration would oppose the motion. Again, acceleration is in the same direction as the change in velocity, which is negative here. This acceleration can be called a deceleration because it has a direction opposite to the velocity. ready mat industries
