The x and y coordinates of the particle at any time are x = 5t – 2t^{2} and y = 10t respectively, where x and y are in meters and t in seconds. The acceleration of the particle at t = 2 s is
0
5 m/s^{2}
-4 m/s^{2}
–8 m/s^{2}
C.
-4 m/s^{2}
x = 5t – 2t^{2} y = 10t
Acceleration of particle at t = 2 s is = –4 m/s^{2}
x = 5t – 2t^{2} y = 10t
Acceleration of particle at t = 2 s is = –4 m/s^{2}
