Question

4. Choose the correct statement
)
A) If the velocity and acceleration have opposite signs, the object is slowing down.
B) If the velocity and acceleration have opposite signs, the object is speeding up.
C) If the velocity is zero at an instant the acceleration should also be zero at that
instant.
D) If the velocity is varying then the acceleration is zero​

Answer 1

Answer:

option d is the answer I think

Answer 2

Answer:

option C is the correct answer as general formula for acceleration is

taking

$a = \ \frac{v - u} {t} \\ taking \: v = 0 \: and \: u = 0 \\ formula \: becomes \: a = \frac{0 - 0}{t}$

therefore if velocity is zero acceleration also becomes zero

hope it helps:)
