An airplane maintains a speed of 630 km/h relative to the air it is flying through, as it makes a trip to a city 750 km away to the north. (a) What time interval is required for the trip if the plane flies through a headwind blowing at 35.0 km/h toward the south? (b) What time interval is required if there is a tailwind with the same speed? (c) What time interval is required if there is a crosswind blowing at 35.0 km/h to the east relative to the ground?

Two objects (m₁ = 4.75 kg and m₂
2.80 kg) are connected by a light string passing over a light, frictionless pulley as in the figure below. The 4.75-kg object is released from rest at a point h = 4.00 m above the table
mg
m
(a) Determine the speed of each object when the two pass each other.
m/s
(b) Determine the speed of each object at the moment the 4.75-kg object hits the table.
m/s
(c) How much higher does the 2.80-kg object travel after the 4.75-kg object hits the table?

A cell of negligible internal resistance is connected to three identical resistors. The
current in the cell is 3.0 A.
The resistors are now arranged in series.
What is the new current in the cell?
