Kinematics

To find the mass of the object, we first need to determine the gravitational potential energy formula, which is PE = mgh (mass x gravity x height). Given the potential energy (PE) as 980 J and height (h) as 5 meters, solve for mass (m) using the formula. The mass of the object would be 40 kg.

To determine speed, you must convert minutes to hours. 1.25 minutes is equivalent to 0.02083 hours (1.25 minutes ÷ 60). Divide the distance (328 yards) by the time in hours (0.02083 hours) to find the speed. Thus, the speed is 15732 yards per hour.

20 mi/h * (1 h / 3600 s) * (5280 ft / 1 mi) = 29.33 ft/sec

Potential Energy is energy that could come from something that if it were to fall (say, from gravity) the kinetic energy gained from that fall would be equal to that. Other forms could be elastic potential energy, chemical potential energy, electrical potential energy (eventually becomes voltage), and etc.

Kinetic energy is of an object that is moving (because I assume we're talking of Newtonain motion).

Boats usually have low friction (drag) compared to freight trains, but they have considerably more drag than most aircraft, especially the really fast ones. The faster the boat or aircraft, the lower the friction.

That depends on how much kinetic energy is present, as well as the design of the car and the type of impact. Specifics?

It depends on Speed of collision and what you mean by destroying. I would say extreme damage is destruction. Otherwise it is only destroying the shape. But remember real destruction never takes place as things take a different shape and still remains..

40/1.6=25 mph

324 km/h is approximately 201 mph. This conversion can be calculated by multiplying the speed in kilometers per hour by 0.621371.

To convert 4 knots to kilometers per hour, you can use the conversion factor of 1 knot is approximately equal to 1.852 kilometers per hour. Multiply 4 knots by 1.852 to get the equivalent speed in kilometers per hour, which would be about 7.408 km/h.

Watt indicator mechanisms are commonly used in steam engines to measure the power output of the engine in watts. This helps engineers monitor the efficiency and performance of the engine and make adjustments as needed. Watt indicator mechanisms typically consist of a pressure gauge and a crank mechanism to measure the pressure and power output of the steam engine.

No, acceleration is not directly proportional to weight. Weight is the force of gravity acting on an object, while acceleration depends on the net force acting on the object, which can be influenced by factors other than weight, such as friction or applied forces.

The kinetic energy (Ek) of the soccer ball can be calculated using the formula: Ek = 0.5 * mass * velocity^2. Plugging in the values, Ek = 0.5 * 1 kg * (10 m/s)^2 = 50 J. The kinetic energy of the soccer ball is 50 Joules.

It's 63.7 meters/second faster than its initial speed, downward, and

63.7 meters/second slower than its final speed, downward.

Without knowing either of those, we can't calculate the specific number.

The first-ever match in the Premier League was played between Sheffield United and Notts County on August 15, 1992. The match ended in a 2-1 victory for Sheffield United.

To find the starting point of a distance vs time graph from a velocity vs time graph and a function, you would integrate the velocity function to find the displacement function. The starting point of the distance vs time graph corresponds to the initial displacement obtained from the displaced function.

No, if an object's velocity is constant, then its speed must also be constant. Velocity is a vector quantity that accounts for both the magnitude (speed) and direction of motion, so if the velocity is constant, both speed and direction will remain the same.

1.5 Meters per Second = 3.36 Miles per Hour

Why don't you relax and tell me something about the situation.

At the maximum height the ball will be completely stopped from moving upward or downward; thus the speed of the ball would be 0 mph. The ball is only stopped for a split second and then it begins moving downward, then increasing at 9.81m/s^2 until it reaches maximum velocity.

Milk being held in a bottle within a gravitational field (above ground, for example) is an example of a substance with potential energy. It has stored energy which will convert into kinetic energy once the milk is poured out, or the container breaks, releasing the milk, and allowing it to accelerate within the gravitational field.

The correct answer is: True. Kinematics ideas are used in a number of different fields, including bio-mechanics (studying how artificial joints work), forensics ( studying how car crashes occurred), and even car racing (determining ideal engine settings, acceleration and braking rates, etc.).

You need to convert the minutes to seconds. Then, simply divide the distance (meters) by the time in seconds.
