Chapter 7: Q. 10 (page 177)

A 3000kgmeteorite falls toward the earth. What is the magnitude of the earth鈥檚 acceleration just before impact? The earth鈥檚 mass is5.98脳1024kg.

Short Answer

Expert verified

The magnitude of the earth鈥檚 acceleration just before impact is 4.9163脳10-21m/s2.

Step by step solution

01

Given information

The meteorite has a mass of 3000kgand its acceleration is 9.8m/s2.The earth has a mass of 5.98脳1024kg.

02

Calculation

Here, the earth has a mass of 5.98脳1024kgand the acceleration of the earth is unknown.

The force of gravity exerted on the meteorite by the earth is the same as the force of gravity exerted on the earth by the meteorite, according to Newton's third law.

So, the force of gravity exerted on the meteorite by the earth is given by:-

localid="1649254099207" F=maF=3000kg脳9.8m/s2F=29400N

The same amount of force is exerted on Earth . Its acceleration is given by:-

F=maa=F/ma=29400N/5.98脳1024kga=4.9163脳10-21m/s2

03

Final answer

The magnitude of the earth鈥檚 acceleration just before impact is4.9163脳10-21m/s2.

Blocks A and B in the figure are connected by a massless string over a massless, frictionless pulley. The blocks have just been released from rest. Will the pulley rotate clockwise, counterclockwise, or not at all? Explain.

Blocks with masses of 1kg,2kgand3kgare lined up in a row on a frictionless table. All three are pushed forward by a 12Nforce applied to the 1kgblock.

a. How much force does the 2kgblock exert on the 3kgblock?

b. How much force does the 2kgblock exert on the1kgblock?

FIGUREEX7.16shows two 1.0kgblocks connected by a rope. A second rope hangs beneath the lower block. Both ropes have a mass of 250g. The entire assembly is accelerated upward at 3.0m/s2by force F鈫�

a. What is F?

b. What is the tension at the top end of rope 1?

c. What is the tension at the bottom end of rope 1?

Two-thirds of the weight of a 1500kg car rests on the drive wheels. What is the maximum acceleration of this car on a concrete surface?

Block Ain FIGUREEX7.5is sliding down the incline. The rope is massless, and the massless pulley turns on frictionless bearings, but the surface is not frictionless. The rope and the pulley are among the interacting objects, but you鈥檒l have to decide if they鈥檙e part of the system.
