Answer:
b
Explanation:
by using formula
a=(v-u)/t
where a= acceleration
v = initial velocity = 10 m/s
u= final velocity =50 m/s
t = time taken = 2s
The acceleration of the rocket has been given by 20 m/[tex]\rm sec^2[/tex]. Thus option B is correct.
Acceleration has been the increase in the speed of the object with respect to the time. The acceleration can be given by:
a = [tex]\rm \dfrac{v\;-\;u}{t}[/tex]
Where,
a = acceleration
v = final velocity = 50 m/s
u = initial velocity = 10 m/s
t = time = 2 s
Substituting the values:
Acceleration = [tex]\rm \dfrac{50\;-\;10}{2}[/tex]
Acceleration = 20 m/[tex]\rm sec^2[/tex]
The acceleration of the rocket has been given by 20 m/[tex]\rm sec^2[/tex]. Thus option B is correct.
