Answer:
0.0102 m or 1 cm
Explanation:
Let g = 10m/s2
The potential energy of the shopping cart of the top of the hill is:
When the cart gets to the bottom of the hill, all this potential energy is converted to kinetic energy:
As the cart stop due to the stump, the can of peaches flies with the same speed.
By Newton's 3rd law, the car would exert a 490N force on the can too
The deceleration of the can would then be:
This force would stop the can, but not without making a dent, aka a traveled distance on the car skin
We can use the following equation of motion to find out the distance traveled by the can:
where v = 0 m/s is the final velocity of the can when it stops, = 40m/s is the initial velocity of the can when it hits, a = -1960 m/s2 is the deceleration of the can, and
is the distance traveled, which we care looking for:
or 1 cm
