Question

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 1

48m

Step-by-step explanation:

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

From Second equation of motion ,

`\longrightarrow` s = ut + 1/2at²

`\longrightarrow` s = 4*4 + 1/2*4*(4)² m

`\longrightarrow` s = (16 + 2 * 16) m

`\longrightarrow` s = ( 16 + 32 )m

`\longrightarrow` s = 48 m
