Chapter 3, Problem 8QAP
To determine

(a)

The angle at which the longest range is achieved by projectile.

To determine

(b)

The angle at which the longest time of flight is achieved.

To determine

(c)

The angle at which the greatest height of flight is achieved.

The angle at which the greatest height is achieved by projectile is θ=90°.

Calculation:

When the projectile will reach maximum height then the vertical component of velocity will be zero,

  vo2sinθ2gh=0h=( v osinθ)22g

The maximum value of h will exist when sinθ=1orθ=90°.

A flat circular coil with 135 turns, a radius of 2.28 x 10-2 m, and a resistance of 0.618 is exposed to an external magnetic field that is directed perpendicular to the plane of the coil. The magnitude of the external magnetic field is changing at a rate of AB/At = 0.615 T/s, thereby inducing a current in the coil. Find the magnitude of the magnetic field at the center of the coil that is produced by the induced current. Number
