Question

A particle P projected from a point O on horizontal ground hits the ground after 2.4 seconds.
The horizontal component of the initial velocity of P is 5/3 d ms-1


The speed of P as it passes over the wall is 16ms-1

(d) Find the value of d correct to 3 significant figures.

May I have the answer for D please as the rules is only to do 3 of them so I asked separately 

b Answered: A particle P projecte X

A particle P projected from a point O on horizon...
Tw=s
S
On dividing the values,
Tw=0.6 s
y=11.76 ms-1
Step 5
On considering let height
wall is h
h = yTw + (5)g(Tw)²
Where,
g is the acceleration due to gravity
On substituting the corresponding values to the above expression,
h = (11. 76) (0. 6) + (0. 5) (–9. 8) (0. 6) (0. 6)
h = 7.056 – 1.764
h = 5. 292 m
Step 6
As per rules supposed to solve only first three subparts of the question so please post the remaining questions
as a separate one
