Question

Which of the following situations is impossible to have? Justify your answer
a)Object moving with variable velocity but fixed acceleration
b)Object moving with uniform velocity but non uniform acceleration
c)Object moving with uniform speed but variable acceleration

Answer 1

Dear Student,

(a) & (c) are possible, but (b) is not possible

(a). When a ball is thrown upwards after reaching a certain height its velocity becomes zero but an constant acceleration , g = 9.8 m/s² acts on it due to gravity downwards.


(c). When the blades of the fan are rotating with a constant speed due to constant change in direction velocity is changing and as velocity is changing so it is acceleration motion but with constant speed.
