A projectile is fired at ?0=394.0 m/s at an angle of ?=68.1∘ , with respect to the horizontal. Assume that air friction will shorten the range by 34.1% . How far will the projectile travel in the horizontal direction, ? ?

Speed v = 394 m / s

Angle θ = 68.1 degree

Range when air friction is negligiable R = v^2 sin 2θ / g
=394^2*sin(2*68.1)/9.8

= 10961.56 m

Range due to air friction R ' = R - 34.1 % of R

= R - 0.341 R = 0.659*R

= 0.659*10961.56

R' = 7223.66 m

A projectile is fired with an initial speed of 36.3 m/s at an

A projectile is fired with an initial speed of 150 m/s and angle
of elevation 60°. The projectile is fired from a position 80 m
above the ground. (Recall g ≈ 9.8 m/s2. Round
your answers to the nearest whole number.)
(a) Find the range of the projectile
(b) Find the maximum height reached.
(c) Find the speed at impact.

A 3.12-kg projectile is fired with an initial speed of 122 m/s
at an angle of 31° with the horizontal. At the top of its
trajectory, the projectile explodes into two fragments of masses
1.04 kg and 2.08 kg. At 3.51 s after the explosion, the 2.08-kg
fragment lands on the ground directly below the point of
explosion.

A small projectile of mass m is fired at an angle θ above the
horizontal. The initial speed of the object is v0. Find the angular
momentum of the projectile with respect to its initial position
when the object is
a) at its initial location;
b) at the highest point of its trajectory;
c) about to strike the ground.
d) What is the source of the torque that changes the angular
momentum of the object?

A projectile is fired at an angle of 28 degrees above the
horizontal with an initial velocity of 1800 feet per second from an
altitude of 1,000 feet above the level ground.
A) Formulate the vector valued function (in simplified form) for
the position of the projectile at any time,t.
B) When and where (in terms of down range distance) does the
projectile strike the ground? Be clear and label your results,
including units.
C) When does the projectile reach...

A
projectile is fired at an upward angle of 380 degrees from the top
of a 105-m-high cliff with a speed of 165m/s. What is its speed
when it strikes the ground below ?

An M-16 is fired from level ground at an upwards angle of 10
degrees with respect to the horizontal. The initial velocity of the
bullet is 948 m/s, but because it is fired at a 10 degree angle,
the vertical component of the initial velocity is 165 m/s and the
horizontal component is 934 m/s. Ignore air resistance and the
curvature of the earth in this problem. (Hint: See the videos
