Question

The displacement 'x' of an object is given as a
function of time t as x = 2 - 4t + 6. Then (consider
all quantities in SI units)
(1) Rate of change of displacement of the object at
t = 0 is 4 m/s
(2) Rate of change of displacement of the object at
t = 1 s is zero
(3) Rate of change of displacement of the object at
t = 0 is – 4 m/s
(4) Both (2) and (3)​

Answer 1

Answer:

the correct answer is only (3) other options are wrong
