Question 160: Motion in 1D

Question

A particle is thrown vertically upward. Its velocity at half of the height is 10 m/s, then the maximum height attained by it (g = 10 m/s2)

Accepted Answer

At height $${h \over 2}$$, speed is = 10 m/s
and at height h, speed  = 0
Using formula,
v
2
= u
2
- 2gh
0 = (10)
2
- 2(10)$${h \over 2}$$
$$ \Rightarrow $$ h = $${{100} \over {10}}$$ = 10 m

Answer

8 m

Answer

20 m

Answer

10 m

Answer

16 m
