Question

the position of particle x depends on time t according to the relation x =(3m/s)t-(1m/s^2)t^2 yhe speed of the particleat t=2 s is​

Answer 1

Answer:

hiiiiiiiiiiiiiiiiiiiiiiiiiiii

Answer 2

Answer:

x=(3m/s)t-(1m/s^2)t^2

x=3t-1t^2

dx/dt=v(speed)

thereforedx/dt=3-2e

therefore at t=2

v=3-2(2)

3-4

=-1m/s
