Kinematics

The formula for kinetic energy is:

KE =( mv2)/2

m= mass (not weight)

v= velocity

A more massive car will have more kinetic energy than a lighter one traveling at the same speed. A faster moving car will have much more kinetic energy than an identical car moving slower.

Ken ran a total of 31.5 miles (4.5 hours * 7 miles per hour = 31.5 miles).

When adding vectors using the head-to-tail method, you place the head of the second vector at the tail of the first vector. The resultant vector is drawn from the tail of the first vector to the head of the second vector. This technique preserves both magnitude and direction of the vectors being added.

If an object travels with zero acceleration, its speed remains constant. This means that the object maintains the same speed throughout its motion and does not change its velocity.

i got 10,022 but im not sure if that's the fastest, i looked up the average and it was 3458 and one eighth

To calculate the distance from a velocity-time graph, you can find the area under the graph. If the graph forms a triangle, you can use the formula for finding the area of a triangle (0.5 * base * height). If the graph forms other shapes, you can break down the area into smaller, more manageable shapes and calculate each separately before summing them up.

falls, as its gravitational potential energy is converted into kinetic energy. This conversion occurs due to the force of gravity acting on the object as it moves downwards.

At 10 miles per hour (MPH), the speed is equivalent to 14.67 feet per second. This is calculated by multiplying the speed in miles per hour by 1.4667 (which is the conversion factor for converting miles per hour to feet per second).

At the top of its path, the vertical component of the projectile's velocity is zero, making the overall speed minimum. This occurs because gravity slows down the projectile's upward motion until it stops momentarily before falling back down. The horizontal component of the velocity remains constant throughout the motion.

Substances can increase their potential energy by absorbing external energy through processes like chemical reactions, phase transitions, or external forces. This added energy causes the molecules or particles within the substance to move further apart or into higher energy states, resulting in an overall increase in potential energy.

The acceleration due to gravity is a constant value of approximately 9.81 m/s^2 for both the book and the rock, regardless of their mass. Therefore, both the book and the rock would accelerate at the same rate and fall at the same speed when dropped from the same height in the absence of air resistance.

The slope of a wavelength vs period graph represents the speed of the wave. A steeper slope indicates a higher speed, while a gentler slope indicates a slower speed.

Vertical acceleration is the rate of change of velocity moving up or down, while horizontal acceleration is the rate of change of velocity moving left or right. Vertical acceleration is affected by gravity, while horizontal acceleration is typically due to external forces like friction or thrust.

90 km per hour = 55.9 mph

About 5.2 knots.

When a vehicle is slowing down, the external force of friction between the brakes and the wheels is what changes its momentum and kinetic energy. This force works against the vehicle's motion, transferring kinetic energy into heat and bringing the vehicle to a stop. The force of the brakes is an internal force that generates friction to slow down the vehicle.

The the forces are unbalanced, that means that the net force is non-zero.

Approximately 102.3 mph at 150 feet per second.

Momentum (P) is the product of mass (m) and velocity (v).

P = m X v

It's easy to get confused by combining metric units (grams) with imperial units (miles per second). Converting all the units to one system first will simplify calculations.

340 kph = 211.26 mph

objects that don't receive any othe force have acceleration a=10m/s, which means their velocity changes. the speed of an object is given by the formula u=V+a*t when the object is falling, and u=V-a*t when the obect is ascending., where u its current speed, V it's starting speed and t the time, and positive direction is down.

through the use of integrals it is proven that its position is x=V*t+(-)a*t/2. this is a parabola graph, so no it is not a straight line.

The car's motor does work to transfer energy, a portion of which is used for purposes other than kinetic energy, such as overcoming friction, air resistance, or internal mechanical losses. Therefore, not all the energy output by the motor contributes to the car's kinetic energy, resulting in a discrepancy between the work done by the motor and the car's kinetic energy.

4,828 kph = about 3,000 miles per hour

The car that is highest has the most potential energy.
