Velocity and acceleration as functions of x

Interactive practice questions

After $t$t seconds, the position of a particle is $x$x metres, its velocity is $v$v m/s and its acceleration is $a$a m/s2.

If $v^2=4-x^2$v2=4x2, express $a$a in terms of $x$x.

After $t$t seconds, the position of a particle from a fixed point is $x$x metres, its velocity is $v$v m/s and its acceleration is $a$a m/s2.

If $v=x+3$v=x+3, express $a$a in terms of $x$x.

The velocity $v$v of a particle at position $x$x can be modelled using the following relationship $v^2=4\left(9-x^2\right)$v2=4(9x2).

Express its acceleration $a$a as a function of $x$x.

After $t$t seconds, the position of a particle is $x$x metres, its velocity is $v$v m/s and its acceleration is $a$a m/s2.

If $\frac{dx}{dt}=e^{4x}$dxdt=e4x, express $a$a in terms of $x$x.
