A Boeing 747 "Jumbo Jet" has a length of 63.2 m. The runway on which the plane lands intersects another runway. The width of the intersection is 24.7 m. The plane decelerates through the intersection at a rate of 5.90 m/s2 and clears it with a final speed of 45.3 m/s. How much time is needed for the plane to clear the intersection?

A Boeing 757 takes off at 2/3 of a runway which is 1800.0 m long. Assume it starts from rest and speeds up uniformly with an acceleration of 2.00 m/s². How long does it take the airplane to take off?

A baseball is hit at a height h = 1.00 m and caught at the same height.  It travels along side a wall moving up past the top of the wall 1.00 s after it is hit and then down past the top of the wall 4.00 s later at distance D = 62 m further along the wall.  Use g = 9.8 m/s/s.     What is the magnitude of the initial velocity?

A soccer ball is kicked at a speed of 14.0 m/s at an angle of 36.0 degrees above the horizontal. The ball is in the air for 2.90 s.What is the maximum height the ball reaches?

A soccer ball is kicked from the ground with an initial speed of 19.6 m/s at an upward angle of 42.4°. A player 54.4 m away in the direction of the kick starts running to meet the ball at that instant. What must be his average speed if he is to meet the ball just before it hits the ground? Neglect air resistance.Use g=9.81 m/s². Number i Unit

Nerve impulses in a human body travel at a speed of about 100 m/s. Suppose a person accidentally steps barefoot on a pebble. About how much time does it take the nerve impulse to travel from the foot to the brain (in s)? Assume the person is 1.60 m tall and the nerve impulse travels at uniform speed.

An airplane undergoes the following displacements: First, it flies 66 km in a direction 30° east of north. Next, it flies 49 km due south. Finally, it flies 100 km 30° north of west. Using vector components, determine how far the airplane ends up from its starting point. A test rocket is fired straight up from rest with a net acceleration of 20.0 m/s2 upwards. After 4.00 seconds the motor turns off, but the rocket continues to coast upward with no appreciable air resistance (deaccelerating). What maximum elevation does the rocket reach during its flight H DELL O W

Nerve impulses in a human body travel at a speed of about 100 m/s. Suppose a woman accidentally steps barefoot on a thumbtack. About how much time does it take the nerve impulse to travel from the foot to the brain (in s)? Assume the woman is 1.80 m tall and the nerve impulse travels at uniform speed.

Roundabout management. The figure below shows an overhead view of a single-lane roundabout where access is computer controlled. Car 1 is allowed to enter at access point A at time t = 0. It accelerates at a = 2.4 m/s² to the speed limit of v = 10.6 m/s as it moves around the roundabout and past access point B where car 2 waits to enter. The radius R of the circular road is 48 m, the angle 8 subtended between A and B is 120°, and both cars have length L = 4.2 m. Car 2 is allowed to enter when the rear of car 1 is 1.9 car lengths past point B. At what time t is car 2 released? Two lanes Car 1 R R One lane B Car 2

A soccer ball is kicked from the ground with an initial speed of 19.5 m/s at an upward angle of 44.3°. A player 53.7 m away in the direction of the kick starts running to meet the ball at that instant. What must be his average speed if he is to meet the ball just before it hits the ground? Neglect air resistance. Use g=9.81 m/s². Number i Unit
