Question

A stone thrown upward reaches 10m and falls back to hand find its distance and displacement

Answer 1

Answer:

displacement is 0

distance is -10 because it falls in backward direction

ek like tho banta he

Answer 2

Answer:

Initial Velocity u=40

Fianl velocity v=0

Height, s=?

By third equation of motion

v

2

−u

2

=2gs

0−40

2

=−2×10×s

s=

20

160

⇒s=80m/s

Toatl distance travelled by stone = upward distance + downwars distance =2×s=160m

Total Diaplacement =0, Since the initial and final point is same.
