Explanation / Answer

1. false
------------------------------
2. true

force F = ma = M(V/t)

so greater the spped, greate the force

so answer is true
-------------------------------------------

3. option b tripled

as Weight W = mg

---------------------------------
4. true
---------------------------------------
5. lesser mass   500 gms
