Answer:
Acceleration of the object will be 
Explanation:
We have given mass of the object m = 9 kg
spring constant k = 95 N/m
Spring is stretched by 10 cm
So x = 10 cm = 0.1 m
We know that force is given by 
From newton's law we also know that force is given by
F = ma , here m is mass and a is acceleration
So 
I'm preeeety sure the answer is A, lost! Hope I helped, hon :)
Answer:
option B.
Explanation:
The correct answer is option B.
when the ball drops, the velocity of the ball before the collision is v
After the collision, the velocity of the ball is the same but in the opposite direction.
Impulse delivered to the ball and the floor, in this case, is not zero.
The magnitude of the momentum remains the same but the direction of the ball changes.
Answer:
0
Explanation:
The displacement is zero since it goes in a full circle and ends up where it started.
