Example 3 suppose that a ball is dropped from the upper observation deck of the cn tower in toronto, 450 m above the ground. find the velocity of the ball after 2 seconds.

225 m/seconds

Step-by-step explanation:

The velocity of an object is the rate of change of the displacement of the object with time measured in m/s. It is similar to speed except that it has a direction and is thus a vector.

Mathematically,

Velocity = Displacement/time

Given that the ball drops 450 m in 2 seconds

Velocity of the ball = 450 m/ 2 seconds

= 225 m/sec

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

x=5

step-by-step explanation:

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76
