Question

position x=t^2-4t+6. find distance and position in 3 seconds

Answer 1

Hello! ! !

Hey dear here is your answer_________

given,

x = t^2 - 4t + 6

differentiate X with respect to t we get,

dx/dt = 2t - 4

we have to find distance in 3 seconds
ie. t = 3

[(dx/dt)at t= 3] = 2 × 3 - 4 = 2

the distance is 2 units.

Now position,
x = (3)^2 - 4(3) + 6

x = 9 - 12 + 6

x = 3

the position x = 3 units
