Question

A
ball is thrown at an angle of 40 degrees above the horizontal at a
speed of 16.0 m/s from the top of a 12.4 m tall bldg. What is the
maximum height of the ball above the ground?

Answer #1

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?

4. A ball is thrown at 20 m/s at an angle of 7 degrees above the
horizon.
a. How far does it reach if it is thrown from a height of 2
m?
b. What would the horizontal component of the velocity be as the
ball hits the ground?
c. What would the overall speed of the ball be as it hits the
ground?

A ball is thrown upward with an initial velocity of 16.0 m/s at
an angle of 50.0 degrees above the horizontal. Use energy
conservation to find the ball's greatest height above the
ground.

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?

A ball at is launched at 30 degrees above the horizontal with an
initial speed at t = 0 of v0 = 1.00 m/s, from an initial
height h0 = 1.00 m above the ground. What is the maximum
height hmax it achieves above the ground, and what is
the time tmax it takes to get there? Show your final
formulas, and the numerical results.

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

A ball is thrown from a point 1.10 m above the ground. The
initial velocity is 19.7 m/s at an angleabove the horizontal. If
the maximum height of the ball aboveground is 7.29 m, what was the
angle atwhich the ball was thrown? Answer in degrees. [Hint:all
information necessary to solve this problemis providedl.]

A ball is thrown with an initial speed of 30m/s at an angle of
45 degrees. Assume the ball is thrown from ground level and lands
on the ground.
a) find the time of flight in secs?
b) find the maxium height in meters?
c) find the distance from where the ball is thrown to where it
lands in meters?
d) find the speed at the impact in meters/sec?

A 4.1-kg ball is thrown from the top of a 4-m tall building
(point A) with a speed of 1 m/s at an angle 2 degrees above the
horizontal. If air resistance is negligible, what is the value of
the kinetic energy of the ball as it hits the ground?

A
100 gram bullet is fired at an angle of 75 degrees above the the
horizontal from the top of a 45 meter tall building with a speed of
60 m/s. Assume no air resistance acts on the bullet and take zero
gravitational potential energy to be at ground level.
A) What is the height of the bullet, measured above the
ground, when 40% of the bullet’s total energy is kinetic
energy?
B) What is the greatest amount of gravitational...
