It would be a relatively simple matter to answer the question

if it included numbers before each appearance of 'ft'.

11.167km per second.

290 kmph is 180.198 mph

1mi = 5280ft

1h = 3600s

3.4mi/h x 5280ft/mi x 1h/3600s = 5.0ft/s (rounded to two significant figures)

It depends on the acceleration of the object.

600 mph is quite fast in scale speed. If you were to scale this speed down to a smaller model or simulation, it would still be considered a rapid pace. However, in real-world applications, 600 mph is slower compared to some high-speed vehicles and aircraft.

If you apply force to the outer edge of the door, this gives you the most leverage.

148 kilometers per hour is 91.96 miles per hour.

Yes:

1 mile = 5280 ft

1 hour = 60 mins

per = divide

Thus:

50mph = 50miles ÷ 1hour

= (50 x 5280 ft) ÷ (1 x 60 mins)

= 4400 ft/min

Velocity does not affect force.

The earth rotates on its axis once each day. Since the circumference of the earth at the equator is 24,901.55 miles, a spot on the equator rotates at approximately 1037.5646 miles per hour (1037.5646 times 24 equals 24,901.55) (1669.8 km/h). At the North Pole (90 degrees north) and South Pole (90 degrees south), the speed is effectively zero since that spot rotates once in 24 hours, a very, very slow speed. To determine the speed at any other latitude, simply multiply the cosine of the degree latitude times the speed of 1037.5646. Thus, at 45 degrees north, the cosine is .7071068 so multiply .7071068 times 1037.5464 and the speed of the rotation is 733.65611 miles per hour (1180.7 km/h). For other latitudes... 10° - 1021.7837 mph (1644.4 km/h)

20° - 974.9747 mph (1569.1 km/h)

30° - 898.54154 mph (1446.1 km/h)

40° - 794.80665 mph (1279.1 km/h)

50° - 666.92197 mph (1073.3 km/h)

60° - 518.7732 mph (834.9 km/h)

70° - 354.86177 mph (571.1 km/h)

80° - 180.16804 mph (289.95 km/h) In addition to the rotational speed of the earth spinning on its axis, the earth is also speeding at about 66,660 miles per hour (107278.87 km/h) in its revolution around the sun once ever 365.2425 days.

Friction always mimics a force in a direction exactly opposite to the object's motion.

So its effect is always to rob the moving object of speed, velocity, kinetic energy,

and momentum.

147 miles per hour is 236.57 kilometers per hour.

The speed at which you fall varies depending on your body position in freefall, your size, your weight and what type of clothing you are wearing.

For instance, the biggest discipline is formation skydiving. This averages around 120mph in a belly to earth body position. Generally, slick nylon type jumpsuits are worn which reduce the drag. In the discipline of freefly, skydivers freefall in a head-up or head-down position. This means they have less drag and therefore fall faster, typically around the 150mph mark.

What stops you continuing to freefall faster and faster is the drag of the air against your body. The higher you jump from, the faster you will fall, but this is not particularly noticable from an average skydiving height of 13,000ft. If you were to triple the altitude, you could expect to noice a dramatic increase in your terminal velocity.

At Skydive Hibaldstow where I jump, it hosts another discipline, speed skydiving. The idea is get the fastest average over a measured vertical kilometer. Winning speeds at the UK Nationals 2010 were around 265mph average.

what is VVT-I

Increase

21 knots is 24.17 mph

It is moving at 0.01944... (recurring) miles per second.

250 mph = 402.34 kph.

a uniaxial force is a force applied only in one direction - directly in the axis direction

A slanting line down from left to right represents an acceleration on the velocity time graph.

1 mile = 1609 meters
1 hour = 60 minutes

so you have

(1.5 miles / 1 hour) X (1609 meters / 1 mile) X (1 hour / 60 minutes)

and from there I'll let you get out your calculator.

A jar lid is typically considered a screw or lever simple machine. The twisting motion used to tighten or loosen the lid acts similar to a screw, while the leverage from the lid helps to create a tighter seal on the jar.
