5t – 3 = 3t –
5t – 3 = 3t –
`4t – 3 – (3t +1) = 5t –
The angle θ covered by a body in rotational motion is give by the equation `θ = 6t + 5t^2 + 2t^3`. Determine the value of instantaneous angular velocity and angular acceleration at time `t =
Given below are some functions of x and t to represent the displacement (transverse or longitudinal) of an elastic wave. State which of these represent (i) a travelling wave, (ii) a stationary wave or (iii) none at all: (a) y = 2 cos (3x) sin (10t) (b) `y = 2sqrt(x-vt)` (c) y = 3 sin (5x – 0.5t) + 4 cos (5x – 0.5t) (d) y = cos x sin t + cos 2x sin
