H, I think. The oil has a lower density than the water, so after the 3 minutes it would float on top of the water.

Answer

Gravity is what holds us down on the earth's (or moon's) surface. If you were to weigh yourself on a scale on Earth and then on the moon, the weight read on the moon would be 1/6 your earth weight

A skateboarder jumps horizontally off the top of a staircase and lands at bottom of the stairs. The staircase has a horizontal l

e-lub [12.9K]

Answer:

The vertical velocity of the skater upon landing is 10.788 meters per second.

Explanation:

Skateboarder experiments a parabolic movement. As skateboarder jumps horizontally off the top of the staircase, it means that vertical component of initial velocity is zero and accelerates by gravity, the final vertical speed is calculated by the following expression:

$v = v_{o} + g\cdot t$

Where:

$v_{o}$ - Initial vertical speed, measured in meters per second.

$v$ - Final vertical speed, measured in meters per second.

$g$ - Gravitational acceleration, measured in meters per square second.

$t$ - Time, measured in seconds.

Given that $v_{o} = 0\,\frac{m}{s}$ , $g = -9.807\,\frac{m}{s^{2}}$ and $t = 1.10\,s$ , the final velocity of the skater upon landing is:

$v = 0\,\frac{m}{s} + \left(-9.807\,\frac{m}{s^{2}} \right)\cdot (1.10\,s)$

$v = -10.788\,\frac{m}{s}$

The vertical velocity of the skater upon landing is 10.788 meters per second.

If air resistance can be neglected, how does the acceleration of a ball that has been tossed straight upward compare with its ac

timama [110]

They are the same. If this is all happening on Earth, then the ball's acceleration is 9.8 m/s^2 in either case. That's the acceleration of gravity around here.
