What is the maximum speed a 1995 Geo Tracker can reach

the maximum speed is around 89

An aeroplane flying at a constant velocity releases a bomb. As the bomb drops down from the aeroplane what will be the position of the bomb with respect to the plane

There are two forces on the bomb when it is dropped; horizontal, and vertical. The vertical force is gravity, and the horizontal force is the velocity of the plane when the bomb is dropped. In order to determine how far away the bomb will drop from the initial point of release, it is necessary to know the height that the plane is at, and the velocity of the plane, which is also the initial horizontal velocity of the bomb (it is constant, neglecting air resistence.)

Does the body falling to the earth travel at the same speed from the very beginning of its travel

No. Its speed keeps increasing as it falls.

A wheel falls off an airplane and takes 8 s to reach the groung if there is no air resistance th ewheels final speed would be

The answer is 78 m/s

Three blocks that are connected by massless strings are pulled along a frictionless surface by a horizontal force

Well it's obviously not flying.

1 A bomber drops a bomb from an aircraft flying at 2000 kmhr at an altitude of 7km The speed at which the bomb will strike the earth would be

equal to 2000 km/hr.

Explain how to find the average speed of a car that travels 300 kilometers in 6 hours

Average speed = Distance travelled/Time spent = 300/6 = 50 km per hour.

A hiker walks 15MI due east then heads due north for 8 KM

a hiker walks 15 mi due east, then heads due north for 8 km. what is the direction of the resultant vector?

What is that thing that EMS workers carry injured people on

There are a variety of devices used to carry patients. Longboard, scoop stretcher, basket stretcher, wheeled stretcher, light stretcher, portable stretcher, stair chair Sometimes we’ll just use a blanket, or do a direct carry.

A body falls frreely what is constant

The acceleration is constant in this case.

What does atomic distance mean

The distance between centers of adjacent atoms

What was the altitude when the bomb was dropped on hiroshima

It exploded at 2000 ft height.

What forces balances the force of gravity on a hanging light

the tension in the rope, string, or wire from which the light is hanging

What is the atomic bomb's terminal velocity

that depends on the bomb casing's shape, not the bomb itself.

What is constant for freely falling body

Acceleration. A free-falling object falls at constant force, and thereby at constant acceleration.

What is the maximum height that the water will reach when water shoots up from the geyser ''Old Faithful'' with a speed of 56 meter per second

The maximum height the water will reach is 157 m.

Is 20 km larger or 500 m

500m is only half a kilometre

What is the acceleration of the system given the value of f and m

Newton's Second Law: F=ma. Solving for a: a = F/m.

What is the highest waterfall in Australla

Wallaman Falls in Queensland with a fall of 300 meters

What determines force of gravity between 2 objects

-- the mass of both objects

-- the distance between their centers of mass

What is the average speed of runner runs 10km in 30 minutes

Speed = Distance / Time = (10 km) / (30 mins) = 0.333 km/min

Now what units do you want?

  • km/hr: (30 mins)(1 hr/60 mins) = 0.5 hr so S = (10 km)/(0.5 hr) = 20 km/hr
What acceleration will a force of 20 newtons cause if applied to a go kart with mass of 20 kilograms

1 Newton = 1 kg·m/s2

Force = mass x acceleration

Acceleration = 20/20 m/ sq sec = 1 m/s2
