Question

speedy drives horizontally off a clif with a velocity of 15 m/s. he lands 30m from the base of the cliff. how high is the cliff?

Answer 1

The height of the cliff is 80 meters.

The rate of change of position of an item in any path. The speed is measured because of the ratio of distance to the time in which the distance was included.

Velocity can be the concept of the charge at which an item covers distance. a quick-shifting item has a high pace and covers a highly huge distance in a given quantity of time, whilst a sluggish-shifting object covers a fantastically small quantity of distance in an identical amount of time.

Motion is a change in the function of an object over the years. motion is defined in terms of displacement, distance, speed, acceleration, time, and speed. speed, being a scalar amount, is the fee at which an item covers distance with respect to time.

Calculation:-

Time = distance/ speed

         = 30/15

          = 2 seconds.

S = ut + 1/2 at²

   = 30 × 2 + 0.5 × 10 × 4

   = 60 + 20

    = 80 meters.
