2. Two person push a `15.0`-`kg`-cart at same time from opposite side as shown below. When the left person uses `25.0\ N` force to push the box, the box is moving toward right with an acceleration of `1.00\ m//s^2`. What is the force push by the person on the right?
2. Two person push a 15.0-kg-cart at same time from opposite side as shown below. When the left person uses 25.0\ N force to push the box, the box is moving toward right with an acceleration of 1.00\ m//s^2. What is the force push by the person on the right?  `sum F = ma`
`F_R = -10.0\ N`
Given:
`F_L = 25.0\ N`
`m = 15.0\ kg`
`a= 1.00\ m//s^2`
`F_R = ?`
Equation:
`sum F = ma`
Solution
`F_L + F_R = ma`
`F_R = ma- F_R`
`F_R = (15.0\ kg)(1.00\ m//s^2)-(25.0\ N)`
`F_R = -10.0\ N` |
