Answer:

b option is better for him

Answer 2

Sand paper would be the best to cover the ramp.

• To stop the car after travelling a small distance we have to apply a surface which creates greater amount of friction.
• Now, a rough surface is a good producer of greater amount of friction.
• In the given options, the sandpaper has the most rough surface. So, it will create maximum amount of friction among the given options.
• That's why, the sand paper would be the best to cover the ramp.
