2. Analyze how target or intended users and audiences are expected to respond to the proposed ICT project for Social Change on the basis of content, value, and user experience

Answer 1

Answer:

56 J

Explanation:

Formula to find the kinetic energy is :

E_kEk = \frac{1}{2}21  × m × v²

Here ,

m ⇒ mass

v ⇒  velocity

Let us solve now

 E_kEk = \frac{1}{2}21 × m × v²

     = \frac{1}{2}21 × 7 kg × ( 4 ms⁻¹ )²

     = \frac{1}{2}21 × 7 × 16

     = \frac{1}{2}21 × 112

     = 56 J
