Question

a particle with uniform acceleration in a straight line has a velocity vms¹ at a position x metre is given by v =√196-16x. it's acceleration is​

Answer 1

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.

form this your answer will be a = -8m/s².

Answer 2

Answer:

-8m/s2 is the correct answer
