Question
If the velocity of a particle is given by m/s, then its acceleration will be:
- Zero
- 8 m/s²
- –8 m/s²
- 4 m/s²
Solution
The acceleration of a particle is given by the derivative of its velocity with respect to time.
Given the velocity function υ = (180 – 16x)^(1/2), we first need to find its derivative with respect to x, which will give us the rate of change of velocity, or acceleration.
The derivative of a function f(x) = (u(x))^(1/2) is given by f'(x) = (1/2) * u'(x) / (u(x))^(1/2), where u'(x) is the derivative of u(x) with respect to x.
Here, u(x) = 180 - 16x. So, u'(x) = -16.
Substituting these values into the formula, we get:
a = f'(x) = (1/2) * (-16) / ((180 - 16x)^(1/2)) = -8 / ((180 - 16x)^(1/2))
So, the acceleration of the particle is -8 / ((180 - 16x)^(1/2)) m/s^2.
Please note that this is the acceleration as a function of x. The actual acceleration at a specific point in time will depend on the value of x at that time.
