Question

A bullet is fired into the air with an initial velocity of 1,400 feet per second at an angle for 45° from the horizontal. What is the horizontal distance traveled by the bullet in 3 seconds? (Neglect the resistance of air on the bullet. Round your answer to the nearest whole number.) ft

Answer #1

45. A bullet is fired
horizontally at a target 10m away. The velocity of the bullet as it
leaves the gun is 100m/s. How much will the bullet drop on its way
to the target. Neglect air resistance.

A cannon is fired at an angle of 50 ° with the horizontal. If
the cannonball has an initial velocity of 757 feet per second, how
far (horizontally) will the shot travel? Assume the initial height
of the projectile is 0 feet, and neglect air resistance.

Assume the acceleration of the object is a(t) = −32 feet per
second per second. (Neglect air resistance.) A ball is thrown
vertically upward from a height of 6 feet with an initial velocity
of 68 feet per second. How high will the ball go? (Round your
answer to two decimal places.)

A ball is thrown vertically upward from a height of 5 ft with an
initial velocity of 83 ft/s. The distance s (in feet) of the ball
from the ground after t seconds is s = s(t) = 5 + 83t − 16t^2. (a)
What is the velocity v, in feet per second, of the ball after 2
seconds?
(b) When, in seconds, will the ball reach its maximum height?
(Round your answer to one decimal place.)
(c) What is...

If the minimum velocity is 30 feet per second, initially
measured at ? = 0 seconds and if the maximum velocity is 50 feet
per second, measured at ? = 5 seconds, how frequently must the
velocity be recorded in order to estimate the total distance
traveled by the LHS and RHS to be within 1 foot of each other?

Use the model for projectile motion, assuming there is no air
resistance and g = 32 feet per second per second.
Determine the maximum height and range of a projectile fired at a
height of 5 feet above the ground with an initial speed of 400 feet
per second and at an angle of 45° above the horizontal. (Round your
answers to three decimal places.)

A baseball is hit from a height of 4.6 feet above the ground
with an initial velocity of 174 feet per second and at an angle of
41 ° above the horizontal. What is the maximum height reached by
the baseball? Neglect air resistance. The fence at the edge of the
field is 9.5 feet tall and located 390 feet from home plate.
Will the ball pass over the fence? No Yes

Arnold hit a golf ball with an initial velocity of 150 feet per
second at an angle of 40° above the horizontal. What is the maximum
height reached by the golf ball?

Use the model for projectile motion, assuming there is no air
resistance and g=32 feet per second per second. A bomber is flying
at an altitude of 30,000 feet at a speed of v= 510 miles per hour
(see figure). When should the bomb be released for it to hit the
target? (Give your answer in terms of angle of depression from the
plane to the target. Round your answer to two decimal places.)
What is the speed of the...

Use the model for projectile motion, assuming there is no air
resistance and g = 32 feet per second per second. Determine the
maximum height and range of a projectile fired at a height of 4
feet above the ground with an initial speed of 600 feet per second
and at an angle of 45° above the horizontal. (Round your answers to
three decimal places.)
maximum height Correct:
maximum range Incorrect:
