Question

Derive the equation if the motion for a particle a)falling vertically b)projected vertically

Answer 1

Answer:

equation of motion under gravity

v= u+gt

s= ut +1/2 at^2

v^2- u^2=2 as

equationof a motion for aparticle falling vertically

v=gt

h=1/2 gt^2

v^2=2gh

equation of a motion for a particle projected vertically

v=u-gt

h= ut-1/2 gt^2

v^2- u^2 =2 gh
