7. A child uses a sled to slide down a very slippery, snowy slope. The sled has a mass of 80 kg and the child has a mass of 35 kg. The top of the slope is 4.0 m higher than the bottom and the sled is travelling at 4.0 m s−1 at the top. Assuming no work is done on the sled by the surface of the slope or the child, what is the speed of the sled (and child) at the bottom of the slope (in m s

Challenging Numerical Triangles
by CodeChum Admin
You probably have encountered Triangle pattern problems before when you started learning programming. Let’s see how well you do with numbers this time. Try to look at the examples closely and think of an algorithm that replicates the outputs. Go for it!

The second line will contain a message prompt to height of the skyscraper.
The succeeding lines will contain the skyscraper pattern.
