A roller coaster is accelerating at 10m/s² before it comes to an abrupt stop at the end of the ride. The mass of the roller coaster is 900 kg. How much force was exerted on the roller coaster to bring it to a stop?

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

force = 900 × 10

We have the final answer as

Hope this helps you

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
