You and your partner want to investigate how the mass of various sports balls will impact their force as they accelerate down a

ramp. You know that objects with more force will roll farther than objects with less force, so for your investigation you will roll three different types of sports balls down a ramp and measure how far they travel before stopping. You can find information about each ball in the table below.

The mass of the ball is inversely proportional to acceleration of a ball.

<h3>What is friction?</h3>

This question is incomplete but I will try to help you the much I can. Friction is the force that opposes motion. Friction depends on the nature of the surfaces in contact.

When the mass of the ball is large, the acceleration of the ball decreases since mass is inversely proportional to acceleration of a body.

A cannonball is fired from a cliff that is 50 meters above the ground. The cannonball is fired horizontally with a speed of 120
tankabanditka [31]

The horizontal distance that the cannonball will travel is 383.33m

In order to find the horizontal distance, we will use the formula for calculating the range expressed as:

R = u\sqrt{\frac{2H}{g} } where:

u is the velocity

H is the height

g is the acceleration due to gravity

R = 120\sqrt{\frac{2(50)}{9.8} }\\R = 120\sqrt{\frac{100}{9.8} } \\R=120\times 3.1943\\R=383.33m

Hence the horizontal distance that the cannonball will travel is 383.33m

Alla [95]

Answer:

Explanation:

1.) What is the net force in the horizontal (x) direction?

Fnet = 8 - 3 = 5 N left

2.) what is the acceleration in the horizontal (x) direction?​

a = Fnet/m = 5/2 = 2.5 m/s² left

emmasim [6.3K]
<span>So we need to put in the correct words to fill in the blanks. The FIRST law of thermodynamics states that energy can't be created or destroyed. It is a formulation of the law of conservation of energy modified for thermodynemical systems. Two natural sources of energy on Earth are the solar and wind. Also geothermal energy and hydropower are natural sources of energy. </span>
