Question

The 'X' and 'Y' co-ordinates of a particle at any
time 't' is given by x = 2t + 4t and y = 5t, where
'X' and 'y' are in metres and l' in seconds. The
acceleration of the particle at t = 5 s, is
(a) zero
(c) 20 ms-2
(d) 40 ms
(e) 8 ms
E/M/D
(b) 16 ms-2
-2
-2​

Answer 1

Answer:

I think 'x' will be 2t²+4t or 2t+4t²...and answer will be ...

8 m/s²
