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

answer: the area of the parallelogram below is 42 square meters.
