Question

If for a particle position x = α t² then –
velocity is constant
acceleration is constant
acceleration is variable
none of these

Answer 1

Answer:

Option (B) Acceleration is constant.

Explanation:

Given that,

x ∝ t²

➡ x = kt² [ Where k is constant ]

➡ Velocity of particle v = dx/dt = 2kt

➡ Acceleration of particle a = dv/dt = 2k

➡ 2k is constant.

Hence Solved!!
