Question

A ball is thrown vertically upwards with an initial velocity of
10 m/s, from a platform that is at a height of 75 m above the
ground. The ball reaches a maximum height and, on the way down,
misses the platform and falls all the way to the ground. Take the
magnitude of the acceleration due to gravity to be 10 m/s2.

(a) What is the velocity of the ball just before it reaches the
ground?

(b) How many seconds is the ball in flight?

(c) What is the maximum height above ground reached by the
ball?

A ball with mass m kg is thrown upward with initial velocity 16
m/s from the roof of a building 28 m high. Neglect air resistance.
Use 9.8 m/s2. Round your answers to one decimal place. (a) Find the
maximum height above the ground that the ball reaches. meters (b)
Assuming that the ball misses the building on the way down, find
the time that it hits the ground.

if a ball is thrown vertically upward with a velocity of 95
ft/s, then its height after t seconds is
s=95t-19t^2
A. what is maximum height reached by the ball?
B. what is the velocity of the ball if its 114 ft above the
ground on the way up?
C. what is the velocity of the ball when it is 114 above the
ground on its way down?

Ball 1 is thrown vertically upwards at 8 m/s from a height of 30
meters from the side a building. A second ball is thrown upwards
from the ground (height of 0 m) 0.39 seconds after the ball 1 is
thrown upwards. With what speed, in m/s, does the second ball need
to be thrown such that it collides with ball 1 when ball 1 is 8
meters above the ground?

A blue ball is thrown upward with an initial speed of 21.2 m/s,
from a height of 0.5 meters above the ground. 2.6 seconds after the
blue ball is thrown, a red ball is thrown down with an initial
speed of 11.7 m/s from a height of 25.7 meters above the ground.
The force of gravity due to the earth results in the balls each
having a constant downward acceleration of 9.81
m/s2.
A) What is the speed of the...

A rock is thrown straight upward from the top of a building with
an initial velocity of 15.0 m/s, at an initial height of 45.0 m
above the ground. The rock just misses the edge of the building’s
roof on its way down. The magnitude of the acceleration due to
gravity is 9.79 m/s2 (in Greeley).a. What is the time needed for
the rock to reach its maximum height?b. What is its maximum height
with respect to the ground?c. How...

A blue ball is thrown upward with an initial speed of 21.4 m/s,
from a height of 0.9 meters above the ground. 2.6 seconds after the
blue ball is thrown, a red ball is thrown down with an initial
speed of 9.2 m/s from a height of 25.3 meters above the ground. The
force of gravity due to the earth results in the balls each having
a constant downward acceleration of 9.81 m/s2.
1) How long after the blue ball...

A ball of mass m is projected vertically upwards at a velocity
v◦. The ball experiences an air resistance force (in addition to
gravity) of the form FR = −αv^2 where α > 0 is constant and v is
the velocity, and reaches a maximum height h before it returns back
to the point of projection. (a) Write down the equations of motion
of the ball during its upward and and downward journeys and show
that the maximum height reached...

A ball is thrown vertically and upwards from a bridge
with a height of 15 m at 10 m / s. Meanwhile, calculate the speed
of the boat as the ball falls into the boat while a boat with a
distance of 15 m from the bridge approaches the bridge with a
constant speed.

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...

A pebble is thrown vertically downwards with a velocity of 5
m/s, and impacts the ground at 10 m/s. If the pebble was thrown
vertically upwards from the same height with the same initial sped,
with what velocity would it impact the ground after falling back
down?
