Question

plz answer my question fast of class 11th

Answer 1

s = 6t + 7

By differentiating with respect to time we can get instantaneous velocity,

So,
ds/dt = d(6t)/dt + d(7)dt
Therefore,
velocity (v) = 6 + 0 = 6

Now, velocity does not remain a function of time. So, velocity becomes constant and is now independent of time.

Hence the velocity at each time i.e 2 s ,3 s, and 4 s will be 6 m/second

hope this helps you !! ^_^
