Answer to Problem 27Q

The rank of all arrows,

ArrowA:M=0.075kgV=16m/sArrowB:M=0.180kgV=12m/sArrowC:M=0.100kgV=18m/sArrowD:M=0.075kgV=12m/sArrowE:M=0.120kgV=10m/sArrowF:M=0.090kgV=16m/sArrowG:M=0.180kgV=10m/sArrowH:M=0.050kgV=8m/s Rank2 Rank3 Rank1 Rank3 Rank4 Rank2 Rank4 Rank5.

Explanation of Solution

Given information:

Eight arrows are given,

ArrowA:M=0.075kgV=16m/sArrowB:M=0.180kgV=12m/sArrowC:M=0.100kgV=18m/sArrowD:M=0.075kgV=12m/sArrowE:M=0.120kgV=10m/sArrowF:M=0.090kgV=16m/sArrowG:M=0.180kgV=10m/sArrowH:M=0.050kgV=8m/s

Concept Used:

Potential energy,

Ep=mgh.

Kinetic energy,

Ek=12mv2.

Calculation:

At ground, potential energy is zero, since the height is zero at ground.

At the highest point, the velocity become zero due to the deceleration affected by the gravity. So, the kinetic energy will be zero at highest point.

According to the law of conservation of energy, the kinetic energy of arrow is completely converted into the potential energy at the highest point. So,

mgh=12mv2hv2

The height is directly proportional to the square of initial velocity.

So, the order arrows based on maximum height is same as the order based on initial velocity.

Thus, the rank for each arrow is,

ArrowA:M=0.075kgV=16m/sArrowB:M=0.180kgV=12m/sArrowC:M=0.100kgV=18m/sArrowD:M=0.075kgV=12m/sArrowE:M=0.120kgV=10m/sArrowF:M=0.090kgV=16m/sArrowG:M=0.180kgV=10m/sArrowH:M=0.050kgV=8m/s Rank2 Rank3 Rank1 Rank3 Rank4 Rank2 Rank4 Rank5.

Conclusion:

The rank of all arrows,

ArrowA:M=0.075kgV=16m/sArrowB:M=0.180kgV=12m/sArrowC:M=0.100kgV=18m/sArrowD:M=0.075kgV=12m/sArrowE:M=0.120kgV=10m/sArrowF:M=0.090kgV=16m/sArrowG:M=0.180kgV=10m/sArrowH:M=0.050kgV=8m/s Rank2 Rank3 Rank1 Rank3 Rank4 Rank2 Rank4 Rank5.

Imagine a planet where gravity mysteriously acts tangent to the equator and in the eastward directioninstead of radially inward. Would this force do work on an object moving on the earth? What is the sign ofthe work, and does it depend on the path taken? Explain by using the work integral and provide a sketch ofthe force and displacement vectors. Provide quantitative examples.
If a force does zero net work on an object over a closed loop, does that guarantee the force is conservative? Explain with an example or counterexample
A futuristic amusement ride spins riders in a horizontal circle of radius 5 m at a constant speed. Thefloor drops away, leaving riders pinned to the wall by friction (coefficient µ = 0.4). What minimum speedensures they don’t slip, given g = 10 m/s²? Draw diagram (or a few) showing all forces, thevelocity of the rider, and their acceleration
