A skydiver free falls from rest. How long does it take for the skydiver to reach 7 m/s?

aev [14]

Answer:

<em>The skydiver needs 0.71 seconds to reach 7 m/s</em>

Explanation:

<u>Free Fall Motion </u>

When an object is dropped in free air (no friction) from a certain height h, it follows a free-fall motion, whose acceleration is due exclusively to gravity. The speed at a moment t when the object is dropped (from rest) is:

$V_f=gt$

We need to find How long does the skydiver needs to reach 7 m/s. We solve for t

$\displaystyle t=\frac{V_f}{g}$

$\displaystyle t=\frac{7}{9.8}$

$t=0.71\ sec$

The skydiver needs 0.71 seconds to reach 7 m/s

A person tosses a ball from the ground up into the air at an initial speed of 10 m/sec and an initial angle of 43° off the groun

Artemon [7]

<h2>Component of the velocity of the ball in the horizontal direction just before the ball hits the ground = 7.31 m/s</h2>

Explanation:

In horizontal direction there is acceleration or deceleration for a ball tossed upward at an initial angle of 43° off the ground.

So the horizontal component of velocity always remains the same.

Horizontal component of velocity is the cosine component of velocity.

Initial velocity, u = 10 m/s

Angle, θ = 43°

Horizontal component of velocity = u cosθ

Horizontal component of velocity = 10 cos43

Horizontal component of velocity = 7.31 m/s

Since the horizontal velocity is unaffected, we have

Component of the velocity of the ball in the horizontal direction just before the ball hits the ground = 7.31 m/s

When is the zebra in motion? When is it not moving?

frosja888 [35]

Motion depends on what your reference point is. So a good reference point is a tree or a sign, something that is not moving. So if the zebra is walking towards the tree he/she is getting closer to the tree, He/she is in motion. But if the zebra and the tree never get closer or farther apart the zebra is not in motion. HOPE THIS HELPED!! ;D
