A loaded grocery cart is rolling across a parking lot in a strong wind. You apply a constant force vecF=(30N)hati-(40N)hatj to the cart as it undergoes a displacement vecs=(9.0m)hati-(3.0m)hatj. How much work does the forces you apply do on the grocery cart ? |
| Answer» SOLUTION :Work= `vecF.vecS=(30xx9)+(40xx3)=390J"""]"` | |
