A rock falls off of a bridge and hits the water 7 seconds later. How fast will the rock be traveling when it hits the water

An arrow is shot straight up at an initial velocity of 250 ms How long will it take to hit the ground

A force of 20 N is applied to a 10 kg mass on a level frictionless surface What is the acceleration of the mass

20 N is applied to 10 kg mass.

20 N/10 = 2.

The acceleration of mass is 2.

A ball is thrown horizontally at 20 ms from the top of a cliff 50 meters high How long does it take the ball to reach the ground

Use the equation [ D = 1/2 g t2 ] .

D = the distance of free-fall = 50 m

g = acceleration of gravity = 9.8 m/sec2

t = time in free-fall

D = 1/2 g t2

2D / g = t2

t = sqrt( 2D / g ) = sqrt( 100 / 9.8 ) = 3.1944 seconds(rounded)

The horizontal velocity that the ball has when it's launched doesn't appear

in the calculation, because it makes absolutely no difference in the result.

Any effects of air resistance have been ignored in arriving at this solution.

What type of measurement A northwesterly wind of 5 miles per hour

vector

It is a meteorological measurement.

Two forces act on the same object One force is pushing due east with a force of 6 newtons and the other is pushing due north at 8 newtons What is the resulting force

10 newtons NE. a little more north than east

A ball is thrown horizontally from a cliff and hits the ground 4 seconds later 40 meters from the base of the cliff How fast was the ball thrown

A golfer tees off and hits a golf ball at a speed of 31 ms and at an angle of 35 degrees How long was the ball in the air

A tennis ball is thrown horizontally at a speed of 10 ms from the top of a building 78.4 meters high How long does it take the ball to hit the street

t=(square root of)(2d/g)

t=2(78.4)/9.8

t=156.8/9.8

t=(square root of)16

t=4 seconds

A ball is thrown horizontally from a cliff at a speed of 15 ms and strikes the ground 45 meters from the base of the cliff How long was the ball in the air

A golfer tees off and hits a golf ball at a speed of 31 ms and at an angle of 35 degrees what is the horizontal velocity component of the ball

What is the vertical component influenced by

A ball is thrown horizontally from a cliff at a speed of 15 ms and strikes the ground 45 meters from the base of the cliff How high was the cliff rounded to the nearest meter

What does the amount of force times the time applied equal

A plane is flying north at a speed of 200 miles per hour The wind is blowing at a constant speed of 40 miles per hour from the east What is the resulting speed of the plane calculated to the nearest

In what type of orbits do planets move around the sun

A player kicks a soccer ball from ground level and sends it flying at an angle of 30 degrees at a speed of 26 ms What is the vertical velocity component of the ball to the nearest ms

What can the moving ball in this illustration be called

A football is thrown horizontally off the top of an apartment house that is 78.4 meters high the ball is thrown at a speed of 15 ms how far will the ball travel before hitting the streets below

What type of measurement is the air pressure inside a tire

What type of measurement is this the speed limit on an interstate highway

A player kicks a soccer ball from ground level and sends it flying at an angle of 30 degrees at a speed of 26 ms

Yes your question is.......................

What term is given to the net figure that results from vector

A Ball Is Thrown Horizontally At 20 Ms From The Top Of A Cliff 50 Meters High How Far From The Base Of The Cliff Does The Ball Strike The Ground

the time it takes to get to ground is s = 1/2 at^2 where a is
gravity acceleration of 9.8 m/s/s and s is 50 meters and t^2 is
time squared.Solve for time t = 3.2 secondsThe horizontal distance
from base of cliff is h = vt where h is distance and v is velocity
= 20 m/sh = 20 x 3.2 = 64 meters

A golfer tees off and hits a golf ball at a speed of 31 ms and at an angle of 35 degrees. What is the vertical velocity component of the ball Round the answer to the nearest tenth of a ms.
