Question

Describe the acceleration in the horizontal and vertical directions for a ball thrown upwards at an angle θ with respect to the horizontal. Address the acceleration as the ball rises, reaches the top of the trajectory, and descends.

Answer #1

1) A ball is thrown at a 60.0° angle above the horizontal across
level ground. It is thrown from a height of 2.00 m above the ground
with a speed of 26.3 m/s and experiences no appreciable air
resistance. The time the ball remains in the air before striking
the ground is closest to
2) A rescue plane flying horizontally at 78.2 m/s spots a
survivor in the ocean 194 m directly below and releases an
emergency kit with a...

A ball is thrown with an initial speed vi at an angle θi with
the horizontal. The horizontal range of the ball is R, and the ball
reaches a maximum height R/8. In terms of R and g, find the
following.
(a) the time interval during which the ball is in motion t =
(b) the ball's speed at the peak of its path v =
(c) the initial vertical component of its velocity yi =
(d)...

Homework 3
As you know very well from physics, if you hit a ball forward with
a certain angle and a certain speed, it makes an orbital
movement.
The height of the ball is determined by the equation given
below.
y(t)=y_0+v_y0 t-1/2 gt^2
Where y0 is the first location of the ball, vy0 is the initial
vertical velocity of the ball and g is the gravitational
acceleration.
After the ball is thrown, the horizontal distance is determined by
the following...

A ball is thrown straight upward and returns to the thrower's
hand after 2.80 s in the air. A second ball thrown at an angle of
43.0° with the horizontal reaches the same maximum height as the
first ball.
(a) At what speed was the first ball thrown?
m/s
(b) At what speed was the second ball thrown?
m/s

A ball is thrown straight upward and returns to the thrower's
hand after 3.10 s in the air. A second ball thrown at an angle of
33.0° with the horizontal reaches the same maximum height as the
first ball.
(a) At what speed was the first ball thrown?
m/s
(b) At what speed was the second ball thrown?
m/s

A
ball is thrown from the roof of a building. The initial velocity
vector is at an angle of 53.0° above the horizontal. It is at
maximum height in 1.04 seconds. Express all vectors in terms of
unit vectors i and j. The ball strikes the ground at a horizontal
distance from the building of 33.1 meters.
a.) What is the vertical velocity (vector) at t=1.04
seconds?
b.) What is the initial vertical velocity (vector)?
c) What is the inital...

A ball is thrown at an angle of 40 degrees to the horizontal
with a speed of 8.0 m/s. After 0.4 seconds the horizontal component
speed is? And after 0.4 seconds the y-axis component speed is?

A ball is thrown in the air at an initial angle 35 degrees above
the horizontal. It takes 4 seconds for the ball to hit the ground.
What is the initial velocity?

1. A ball is thrown upwards from the top of a building at an
angle of 37degress to the horizontal with a speed of 20 m/s.
components of initial velocity are x=15.9m/s y=12m/s. What are the
components of velocity when it hits the ground? (x=15.9m/s but I
cannot figure out y) HELP HERE PLEASE!
2. While pecking on a tree, a woodpeckers brain comes to a stop
from an initial velocity of .6 m/s in a distance of 4mm a=45m/s^2...

A ball is thrown with velocity of 50 ft/sec directed 60 degrees
with the horizontal against a vertical wall. The ball is released
from a position 40 ft from the wall and 6 ft above the level ground
and travels in the vertical plane. e is 0.6. How far will the ball
strike the ground?
