Answer:

Explanation:

According to Newton's second law, acceleration is directly proportional to the net force. As the acceleration increases (when mass is constant), the net force increases. This is represented in the following formula.

$f = ma$

$a = \frac{f}{m}$

a = acceleration

f = force

m = mass

A 66-kg bicyclist (including the bicycle) accelerates uniformly from 0.50 m/s to 1.50 m/s, traveling 6.0m. What is the net force

FromTheMoon [43]

The net force acting on the bicyclist is 11.022 Newton.

Given the following data:

Mass of bicyclist = 66 kg

Initial velocity = 0.50 m/s

Initial velocity = 1.50 m/s

Distance traveled = 6.0 meters

To find the net force acting on the bicyclist, we would apply Newton's Second Law of Motion:

Mathematically, Newton's Second Law of Motion is given by this formula;

$Force = mass$ × $acceleration$

First of all, we would determine the acceleration by using the third equation of motion;

$V^2 = U^2 + 2aS\\\\1.5^2 = 0.5^2 + 2a(6)\\\\2.25 = 0.25 + 12a\\\\12a = 2.25 - 0.25\\\\12a = 2\\\\a = \frac{2}{12}$

Acceleration, a = 0.167 $m/s^2$

Now, we can find the net force acting on the bicyclist:

$Force = 66$ × $0.167$

Force = 11.022 Newton

Therefore, the net force acting on the bicyclist is 11.022 Newton.

An object is propelled along a straight-line path by a force. If the net force were doubled, the object's acceleration would be_

nikdorinn [45]

Answer:

double

Explanation:

According to the newton's second law

force = mass x acceleration

So, acceleration is directly proportional to the force.

As the force is doubles, the acceleration is also doubled.

What is force of gravity

Eduardwww [97]

Answer:

On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects. At Earth's surface the acceleration of gravity is about 9.8 metres (32 feet) per second per second.
