Question

A particle is thrown at an angle to horizontal from o and it hits the ground

Answer 1

Given that a particle is thrown with angle of projection

θ

over a triangle

Δ

A

C

B

from one of its end

A

of the horizontal base

A

B

aligned along X-axis and it finally falls at the other end

B

of the base,grazing the vertex

C

(

x

,

y

)

Let

u

be the velocity of projection,

T

be the time of flight,

R

=

A

B

be the horizontal range and

t

be the time taken by the particle to reach at C

(

x

,

y

)

The horizontal component of velocity of projection

→

u

cos

θ

The vertical component of velocity of projection

→

u

sin

θ

Considering motion under gravity without any air resistance we can write
