ball is thrown vertically upward from an initial position 5m above the ground. At the same time, a cube is released from rest down aslippery incline, from an unknownheight. The two objects reach the ground at the same instant, and both have a final speed of 15m/s. What is the angle ofthe incline

The value is

Explanation:

Generally the time it takes the ball to move from maximum height to the ground is

Here u= 0 m/s and v = 15 m/s

So

=>

Generally the maximum height traveled in time t is mathematically represented as

=>

=>

The interval in distance between the maximum height and the initial position of the ball is

Here k = 5 m (given)

Generally from the kinematic equation we have that

Here is the time taken to travel through d

=>

=>

Generally the total time for this fight is mathematically represented as

=>

=>

Generally the vertical force exerted on the cube is mathematically represented as

=>

=>

Now a is mathematically represented as

=>

=>

So

i'm on my way to history not a mistory.

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
