The 3kg object in figure is released from rest at height of on a curved frictionless ramp. at the foot of the ramp is a spring o

f force constant 400N/m. the object slides down the ramp and into the spring,compressing it a distance x before coming momentarily to rest.
a) find x
b) describe the motion of the object (if any) after the block momentarily comes to rest?

(a) The compression of the spring is 7.4 cm.

(b) When the object comes to rest its potential energy from the given height will be converted into elastic potential energy of the spring.

<h3>Compression of the spring [ x ]</h3>

The compression of the spring is calculated by applying Hooke's law as follows;

F = kx

x = F/k

x = (mg)/k

x = (3 x 9.8)/400

x = 0.074 m

x = 7.4 cm

When the object comes to rest its potential energy from the given height will be converted into elastic potential energy of the spring.

Identify the situations that have an unbalanced force. Check all that apply. A baseball speeds up as it falls through the air. A
viktelen [127]
<span>A baseball speeds up as it falls through the air.
Yes.  Forces on the balloon are unbalanced. 
The balloon is speeding up, so we know that the downward force
of gravity is stronger than the upward force of air resistance.

A soccer ball is at rest on the ground.
No. The ball is not accelerating, so we know that the forces on it
are balanced.
The downward force of gravity on the ball and the upward force
of the ground are equal.


An ice skater glides in a straight line at a constant speed.
No. The skater's speed and direction are not changing, so he is not
accelerating.  That tells us that the forces on him are balanced.

A bumper car hit by another car moves off at an angle.
Yes.  The direction in which the car was moving changed. 
That's acceleration, so we know that the forces on it are unbalanced,
at least at the moment of impact. 

A balloon flies across the room when the air is released.
Yes.  The balloon was not moving. But when the little nozzle was
opened, it started to zip around the room.  So its speed changed.
And, as it goes bloozing around the room, its direction keeps changing too. 
There's a whole lot of acceleration going on, so we know the forces on it
are unbalanced.</span>
