calculate acceleration of plane that moves from a stop position to a speed of 55 m/s in 5 seconds. (55m/s - 0m/s )/5s = 11m/s²
an airplane is flying west at 200 km/hr. two hours later, it is flying west at 300 km/h. its average acceleration is 100 km/h. a speed vs. time graph for a car's motion is a horizontal line at a speed of 12 m/s. the cars acceleration during this time is 12 m/s².
An object experiences a uniform circular motion in a horizontal plane, as illustrated. The direction of the net force is: A small ball attached to the end of a string experiences a uniform circular motion on a horizontal frictionless table.
A car moves around a circular path of a constant radius at a constant speed. Which statement is true? A car moves around a circular path of a constant radius at a constant speed. When the car is at the top of the circular path what is the direction of the velocity?
An airplane whose airspeed is 200 km/h is flying in a wind of 80 km/h. The airplane's speed relative to the ground is between. 120 and 280 km/h. A ship travels 200 km to the south and then 400 km to the west. The ship's displacement from its starting point is. 450 km.
friction between the tires and the road. The centripetal force that keep the earth in its orbit around the sun is provided. entirely by the gravitational pull of the sun. The gravitational force with which the earth attracts the moon. is the same as the force with which the moon attracts the earth.
the satellite is falling toward the earth just as fast as the astronaut is, so there is no upward reaction force on him or her. A bicyle travels 12 km in 40 min. Its average speed is. 18 km/h.
Two objects have the same size and shape but one of them is twice as heavy as the other. They are dropped simultaneously from a tower. If air resistance is negligible. You are riding a bicycle at constant speed when you throw a ball vertically upward.
A plane is flying horizontally at a height of 500 m and a constant speed of 429 km/h when an object is projected vertically downward at an initial speed of 35.0 m/s. If air resistance is neglected, the average vertical component
The pilot of an aircraft flying horizontally at a speed of 1200 Km/hr observes an angle of depression of a point on the ground changes from 30 degree to 45 degree in 15 seconds. Find the height of the aircraft at which it is
A cargo plane is flying horizontally at an altitude of 10000m with a velocity of 800km/h when a cargo pallet falls out the back ramp. (i) How long does it take to fall to the ground? (ii) How far horizontally is the pallet from
A plane flying horizontally at an altitude of 2 mi and a speed of 420 mi/h passes directly over a radar station. Find the rate at which the distance from the plane to the station is increasing when it is 5 mi away from the
A rescue plane is flying horizontally at a height of 132 m above the ground . The pilot spots a survivor and releases an emergency kit with a parachute. The kit descends at a constant vertical acceleration of -6.89 m/s^2 and the
A plane takes off at an angle of 20 degrees. Assuming a constant speed and trajectory, by the time it has travelled 25 kilometres horizontally, how high will it be flying?
Have you ever been on an airplane and heard the pilot say that the plane would be a little late because it would be flying into a strong headwind or that even though the plane was taking off a bit late, you would be making up time.
