• ## Question: A ball is thrown vertically upward. At the highest point in its path, which of t...

Posted in: Physics | Date: 24/11/2017

Acceleration=force/mass , in above mentioned case gravity is acting continuously on the object hence acceleration with be non zero, and at the highest point object will be in momentarily rest hence velocity will be zero. Hence the correct option is A

• ## Question: On velocity-time graph when two curves coincide, the objects will have

Posted in: Physics | Date: 24/11/2017

Correct answer is B. In velocity time graph , velocity is plotted against time . If two curve coincide then they will share same co-ordinates I.e same velocity at a time instant . These two curves may have different slope at that point i.e they can have different acceleration (slope of v-t curve is acceleration) , hence option B is correct
