Homework Statement
a toy is dragged along a rough floor by a child
(a) when the child applies a force of 0.50N horizontally the velocity is contant at 1.0 m/s. What is the force of friction on the toy?
(b)when the child pulls harder so that the applied force is 1.00N the velocity of the toy increases uniformly to 2.0 m/s in 5.0 seconds. Calculate the acceleration of the block.
(c) find the mass of the toy
Homework Equations
(a) Do I have to use the frictional force equation to find the answer? (Ffric = μ* F norm)
(b) should I use the net force equation? Fnet=M*A
The Attempt at a Solution
(A)I was considering using the frictional force equation to solve the problem but I don´t have all the variables
(B) Velocity v Time graph perhaps?
thanks for the help (I´m a noob in physics)
