# A golf club is swung and strikes a golf ball with a force of 12.2 N. The golf ball accelerates at 265.2 m/s2 (wow) Determine the mass of the golf ball.

F = m A  (Newton #2)

m = F/A

m = (12.2 N) / (265.2 m/s²)

m = (12.2 / 265.2) kg

m = 0.046 kg

(46 grams;  not bad; the international standard is "not more than 45.93 grams")

Note:  265.2 m/s² = about 27 G's .  Seems to me like that would rip the ball to shreds, but I don't really know anything about golf.)

What is the average speed of a car that traveled 300.0 miles in 5.5 hours?

The average speed of will be "0.41 m/s".

Speed and Distance:

According to the question,

Distance = 300.0 miles

Time = 5.5 hours

We know,

miles = meters

Now,

By converting 5.5 hours into seconds, we get

=

=

hence,

The speed will be:

54.54 miles per hour

Explanation:

You do 300 divided by 5.50 to get 54.545454 but you can estimate it to be about 54.54 miles per hour.

So, top average speed of car was 54.54 mph.

Which of the following is the correct SI unit to use in measuring amount of material contained in a solid sphere? A) kilograms B) ounces C)pounds D)tons

Explanation:

The amount of matter in a body is defined as mass, which is a physical quantity that expresses the measure of inertia of a body, determined by the acceleration produced when a force acts on it.

The unit of mass in the International System of Units (SI) is the kilogram, which was defined for many years from a standard object (the international prototype of the kilogram located at the International Office of Weights and Measures). However, since of May 20, 2019, its definition became linked to Planck's constant

What’s the kinetic energy of the roller coaster at the top and bottom of the hill? Use . A kiddie roller coaster car has a mass 100 kilograms. At the top of a hill, it’s moving at a speed of 3 meters/second. After reaching the bottom of the hill, its speed doubles. The car’s kinetic energy at the bottom is its kinetic energy at the top. The car has joules of kinetic energy at the bottom of the hill.

The kinetic energy of the roller coaster at the top and bottom of the hill is 450 J.

What is kinetic energy?

Kinetic energy is the energy an object possesses due to its motion.

It is defined as the work needed to accelerate an object of a given mass from rest to its current velocity.

The formula for kinetic energy is

KE = 1/2 ×m × v²

Where

KE = the kinetic energy,

m= the mass of the object,

v= its velocity.

Kinetic energy is a scalar quantity and is measured in joules (J) in the International System of Units (SI). The greater an object's mass and velocity, the greater its kinetic energy. This energy can be transferred to other objects or transformed into other forms of energy through various processes, such as collisions or friction.

Here in this question,

The kinetic energy of an object is given by the formula:

KE = 1/2 ×m × v²

where KE is the kinetic energy, m is the mass of the object, and v is its velocity.

At the top of the hill, the roller coaster car has a kinetic energy of:

KE_top = 1/2 × 100 kg × (3 m/s)²

= 450 J

At the bottom of the hill, the roller coaster car has a velocity of 2 × 3 m/s = 6 m/s.

Since the car's kinetic energy at the bottom is equal to its kinetic energy at the top, we can set the two formulas for kinetic energy equal to each other and solve for v:

1/2 ×100 kg × (3 m/s)² = 1/2 × 100 kg ×v²

v² = (3 m/s)²

v = 3 m/s

so, the roller coaster car's velocity at the bottom is still 3 m/s, and its kinetic energy is:

KE_bottom = 1/2 ×100 kg× (3 m/s)²

= 450 J

Therefore, the roller coaster car has 450 joules of kinetic energy at both the top and bottom of the hill.
