Acceleration (a)= 5.71

Time= 15.46 seconds

Explanation:

A.) Time

1.) Through derivation, we will be able to determine that the formula for time is:

2.) Substitute the values:

3.) Through basic algebra, we will get this

B.) Acceleration

1.) The basic formula for acceleration is:

2.) Subsitute the values

*Notes:

1.) Your question stated no initial velocity, only the final velocity

2.) The value we inputted for time is the one that we solved for in section A

Explanation:

In some of the isolated places in the Philippines, relief goods are delivered using helicopter. A helicopter moving horizontally with a constant velocity of 120 m/s at an altitude of 1200 m. The plane releases a “care package” that falls to the ground along a curved trajectory. Ignoring air resistance, (a) determine the time required for the package to hit the ground. Suppose that the plane is travelling with twice the horizontal velocity (240 m/s), (b) determine the time required for the package to hit the ground

Question :

A plane has a takeoff speed of 88.3 m/s and requires 1365 m to reach that speed. Determine the acceleration of the plane and the time required to reach this speed.​

vi = 0 m/s

vf = 88.3 m/s

d = 1365 m

vf² = vi² + 2*a*d

(88.3 m/s)² = (0 m/s)² + 2*(a)*(1365 m)

7797 m²/s² = (0 m²/s²) + (2730 m)*a

7797 m²/s² = (2730 m)*a

(7797 m²/s²)/(2730 m) = a

a = 2.86 m/s²

vf = vi + axt

88.3 m/s = 0 m/s + (2.86 m/s²)*t

(88.3 m/s)/(2.86 m/s²) = t

t = 30. 8 s

Distance = 1365m

Initial velocity = 0(starts from rest)

Final velocity = 88.3m/s

V sqr = u sqr +2as

88.3 sqr = 0 + 2 (1365)a

7796.8 = 2739.a

a = 7796.8/2739

a=2.856m/sec sqr

V= u+at

88.3 = 0+2.856.t

t=2.856/88.3

t=30.917 seconds

Hope u understand
