Homework Statement
A force applied to a tennis ball is described by the function
F(x) = 2x + 5, with the force in Newtons and the position in meters.
How much work does the force do on a tennis ball as it moves from -2.5 m to a new position of 2.4 m?
Homework Equations
F(x)= 2x+5
force x distance= work
The Attempt at a Solution
I found the distance from -2.5m to 2.4m which is 4.9m.
Then I plugged -2.5m into x for the function which is 0.
I then plugged in 2.4m into the function which is 9.8.
With 9.8, I multiplied it by 4.9 m getting 48.02 which is incorrect
Can anybody find my error? Thanks!
