We need to use the equation for potencial energy

Ep= mgh

now we have to replace with the values we have

Ep=(14m)(9.81m/s²)(0.01kg)

Ep= 1.3734 Joules

A ball is thrown with a speed of 20 m/s at an angle of 40o above the horizontal from the top of a 22-m tall building.
MrRissso [65]

Answer:

(a). The distance is  49.79 m.

(b). The speed of the ball is 24.39 m/s.

Explanation:

Given that,

Speed = 20 m/s

Angle = 40°

Height = 22 m

Time = 3.25 sec

(a). We need to calculate the distance

Using formula of distance

d=u\cos\theta\times t

Put the value into the formula

d=20\cos40\times3.25

d=49.79\ m

(b). We need to calculate the horizontal velocity

Using formula of velocity

v_{x}=u\cos\theta

Put the value into the formula

v_{x}=20\times\cos40

v_{x}=15.3\ m/s

We need to calculate the vertical velocity

Using equation of motion

v_{y}=u\sin\theta-gt

Put the value into the formula

v_{y}=20\sin40-9.8\times3.25

v_{y}=-19\ m/s

Negative sign shows the opposite direction.

We need to calculate the speed of ball

Using formula of speed

v=\sqrt{v_{x}^2+v_{y}^2}

v=\sqrt{(15.3)^2+(19)^2}

v=24.39\ m/s

Hence, (a). The distance is  49.79 m.

(b). The speed of the ball is 24.39 m/s.

enyata [817]
Teens drink mostly because the people/media around them tell them its "cool" and to be liked you have to drink, or "why miss out on the fun?" "Are you scared?" They are pressured into the idea that if they want to be cool or liked, they need to drink.
I'm not in Florida, so I wouldn't know your specific laws, but I know that driving under the influence is pretty much illegal in every state, and you will have consequences if you are caught.
Hope this helps!
