Question

if velocity of particle is given by b is equals to (180 - 16 x)
^1/2metre per second then its acceleration will be
​

Answer 1

Answer:

-8m/s²

Explanation:

If the velocity of a particle is given by v= (180-16x) ^1/2 m/s then its acceleration will be

v = √(180 - 16x)

v² = 180 - 16x

Differentiate with dt

2vdv/dt = -16 dx/dt

2va = -16v

a = -8m/s²
