Aball is thrown horizontally at a height of 2.2 meters at a velocity of 65m/s off a cliff. assume no air resistance. how long until the ball reaches the ground?

We have that A ball is thrown horizontally at a height of 2.2 meters at a velocity of 65m/s off a cliff. Assuming no air resistance will take t to reach the ground

t=0.670sec

From the question we are told that

A ball is thrown horizontally at a height of 2.2 meters

a velocity of 65m/s off a cliff

Generally the equation for the Time is mathematically given as

s=ut+1/2gt^2

Therefore

Therefore

A ball is thrown horizontally at a height of 2.2 meters at a velocity of 65m/s off a cliff. Assuming no air resistance will take t to reach the ground

t=0.670sec

The horizontal motion has no effect on the vertical drop.

From a drop, the distance the ball falls in 'T' seconds is

D = 4.9 T^2

so

2.2 = 4.9 T^2

T^2 = 2.2/4.9

T^2 = 0.449 sec^2

T = 0.67 second

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
