A shopping cart is given an initial velocity of 4 m/s and experiences a constant acceleration of 4 m/s2. What is the magnitude of the cart’s displacement after the first 4 s of its motion?

Answer:

48m

Explanation:

  • Initial velocity = 4m/s
  • Acceleration = 4m/s²
  • Time = 4s
  • Displacement = ?

From Second equation of motion ,

[tex]\longrightarrow [/tex] s = ut + 1/2at²

[tex]\longrightarrow [/tex] s = 4*4 + 1/2*4*(4)² m

[tex]\longrightarrow [/tex] s = (16 + 2 * 16) m

[tex]\longrightarrow [/tex] s = ( 16 + 32 )m

[tex]\longrightarrow [/tex] s = 48 m
