Please help really desperate as it is due in a couple of hours.

A cricket ball is hit from a point A with velocity of (pi + qj)ms-1 at an angle theta above the
horizontal, i and j are the unit vectors horizontally and vertically upwards respectively. The point
A is 0.8 m vertically above the point 0, which is on horizontal ground.
The ball takes 4 seconds to travel from A to B, where B is on the ground and OB = 64 m, as
shown in the diagram. By modelling the motion of the ball as that of a particle moving freely under gravity,
a) find the value of p and the value of q

b) find the initial speed of the ball

c) find the exact value of tan theta

d )find the length of time for which the cricket ball is at least 5 m above the ground.

e )State an additional physical factor which may be taken into account in a refinement of the above model to make it more realistic.​​

Answers

Answer 1
the answer is b, fine the initial speed of the ball

Write an
explicit formula for An, the nth term of the sequence 7, -42, 252, ....

Answers

Answer:

[tex]A_n = 7(-6)^{n-1}[/tex]

Step-by-step explanation:

Key skills needed: Explicit formula, Geometric sequence

1) This is a geometric sequence, meaning a constant (like 6 or 3.5) is being multiplied to every term. First we need to find the constant.

This can be done by doing -42 ÷ 7   or   252 ÷ -42

-42 ÷ 7 equals -6.

252 ÷ -42 also equals -6.

2) This means that constant is -6.

3) The general form for an explicit formula of a geometric sequence is:

[tex]a_n = a_1(r)^{n-1}[/tex]

--> r means the constant (or common ratio) that is being multiplied.

--> [tex]a_1[/tex] means the first term

--> [tex]a_n[/tex] means the "nth" numbered term (so [tex]a_3[/tex] is the 3rd term, [tex]a_{10}[/tex] is the 10th term and so on).

--> [tex]n-1[/tex] is just the "n" in [tex]a_n[/tex] minus 1.

4) We can use this formula to create an explicit formula for the geometric sequence in the problem.

--> [tex]r = -6[/tex] (Since we got -6 as the constant/common ratio).

--> [tex]a_1 = 7[/tex] (Since 7 is the 1st term)

This means that our formula would be --> [tex]A_n = 7(-6)^{n-1}[/tex]

Hope you understood and have a nice day!! :D

5x + 2y = -3
3x + 3y = 9​

Answers

Answer:

Step-by-step explanation:

5x + 2y = -3

3x + 3y = 9

15x + 6y = -9

-15x - 15y = -45

-9y = -54

y = 6

5x + 2(6) = -3

5x + 12 = -3

5x = -15

x = -3
