Question

If a block moving up at 0 = 30° with a velocity 5 m/s, stops
after 0.5 sec, then u is
(a) 0.5
(c) 0,6
(b) 1.25
(d) none of the above.​

Answer 1

Answer:

a)0.5 okkkkkkkkkkkkkkk

Answer 2

• tan 30degree =1/
• $\sqrt{3}$
• i.e acceleration
• v=5
• t=0.5
• v=u-at
• u=v+at
• u will get the ans
• $1 \div \sqrt{3 }$
• $\times 0.5$
• $+ 5$
