Question

the position x of a particle moving along a straight line is given by x=2-5t+6t*t find velocity and acceleration due to gravity

Answer 1

x=2-5t+6t^2 m

v=dx/dt
v=d/dt(2-5t+6t^2)
v=12t-5 m/s

a=dv/dt
a=d/dt(12t-5)=12 m/s^2

Answer 2

Answer:

12 m/s^2

Explanation:

• v=dx/dt
  v= 0-5+2×2t
  v=12t-5
  v=24-5
  v=19
  
  
  a=dv/dt
  a=d/dt(12t-5)
  =12 m/s^2
