Question

If at an instant t=0,
Can instantaneous velocity be greater than zero?
If not, then how can be
$\frac{dx}{dt} = \frac{d}{dt} \times (a + bt ^{2} ) = 5$
Given t=0, a=8.5m, b=2.5m/s^2
​

Answer 1

Answer:

yes the instantaneous velocity of any object at t=0 can be greater than zero

Step-by-step explanation:

The instantaneous velocity at time t=0 , happens at the maximum of the position function. If slope of the position graph is zero, then the instantaneous velocity is zero.
