A ball is thrown straight up. It passes a 2.00-m-high window 7.50 m off the ground on its path up and takes 1.30 s to go past th

OLga [1]

Answer:

u = 13.67 m/s

Explanation:

given,

window height = 2 m

window is 7.5 m off the ground on its path up

total distance from the ground to pass the window = 2 + 7.5 = 9.5 m

time taken to go past the window = 1.30 s

using equation of motion

$S = u t +\dfrac{1}{2}gt^2$

$(2+7.5)= u\times 1.3 -0.5\times 9.8\times 1.3^2$

$u\times 1.3 = 9.5 + 8.281$

u = 13.67 m/s

hence, the initial velocity of the ball is equal to 13.67 m/s

ILL GIVE THE BEST ANSWER BRAINLIEST I PROMISE AND ILL THANK EVERY ANSWER A polar bear is able to walk on ice without breaking it

krek1111 [17]

Answer:

Polar bears (Ursus maritimus) are of special interest because of their large size, white color and position as the top-level carnivore in the remote arctic environment. They occur only in the northern hemisphere nearly always in association with sea ice. They have only two colors of fur: tan and white. Polar bears were created to withstand cold temperatures and are quite adaptable. Polar bears are ferocious and the most dangerous of bears. They can lop a person's head off with one swoop of their paw.

An ice skater starts with a velocity of 2.25 m/s in a 50.0 degree direction. After 8.33s, she is moving 4.65 m/s in a 120 degree

Westkost [7]

Answer:

Explanation:

Lets decompose the initial velocity into its components:

Vi = 2.25 m/s

Vix = Vi x cos(50)

Viy = Vi x sin(50) = 2.25 x sin(50) = 1.724

Then decompose the final velocity:

Vf = 4.65

Vfx = Vf x cos(120)

Vfy = Vf x sin(120) = 4.65 x sin(120) = 4.027

After that we can use:

Vfy = Viy + ay*t

ay = (Vfy - Viy)/t

ay = (4.027 - 1.724) / 8.33

ay = 0.276

If a net horizontal force of 175 N is applied to a bike whose mass is 50 kg what acceleration is produced?

Crazy boy [7]

The acceleration of the bike is $3.5 m/s^2$

Explanation:

We can solve this problem by using Newton's second law of motion, which states that:

$F=ma$

where

F is the net force on an object

m is the mass of the object

a is its acceleration

For the bike in this problem, we have

F = 175 N is the net force

m = 50 kg is the mass

And solving for a, we find the acceleration:

$a=\frac{F}{m}=\frac{175}{50}=3.5 m/s^2$
