9/8: Warm Up 9/8: Warm Up Record your answer here: You can find the net force F on an object by using the formula F = ma F m is the mass of the object in kilograms a is its acceleration (meters per seconds squared. What is the mass of an object that has: a net force of 65 kg m/s2 an acceleration of 5 m/s2 M A top and bottom- divide bottom and bottom- multiply

9/9 Warm Up 9/9 Warm Up Write an equation to solve the problem. A T-shirt maker wants to open his first store. If he chooses the store on Main Street, he will pay $640 in rent and will charge $30 per T-shirt. If he chooses the store on Broad Street, he will pay $450 in rent and will charge $25 per T-shirt. How many T-shirts would he have to sell in 1 month to make the same profit at either location?
