A boy pushes a box of mass 2 kg with a force F → = 20 i ^ + 10 j ^ N on a frictionless surface. If the box was initially at rest, then _______ m is displacement along the x -axis after 10 s

Step-by-step solution

F → = 20 i ^ + 10 j ^ a → = F → m = 20 i ^ + 10 j ^ 2 ⇒ 10 i ^ + 5 j ^ ∴   s → = 1 2 a → t 2 = 1 2 10 i ^ + 5 j ^ × 10 2 ⇒ 50 10 i ^ + 5 j ^ m ∴ Displacement along x -axis ⇒ 50 × 10 ⇒ 500   m
