VERY IMPORTANT FOR AN ESSAY ASSIGNMENT. PLEASE HELP ASAP! THANK U VERYYYYY MUCH!
1. What force is needed to give a mass of 25 kg an acceleration of 20m/s squared?
2. A force of 6N acts upon a 2-kg mass. What is the acceleration of the masS?
3. It takes a force of 50N to give a body an acceleration of 10m/s squared. What is the mass of the body?
4. a) what is the weight of a 10-kg piece of iron?
b) what is the mass of an object that weighs 490N?
Hi Nicola-
I am not a physicist; however, I believe you can work all of your problems, as DrWLS suggested, with F=ma.
since force is equal to mass × acceleration now question one answer is 25×20=500
Hi! I'd be happy to help you with your essay assignment. Let's go through each question and I'll explain how to solve them:
1. To find the force needed to give a mass of 25 kg an acceleration of 20 m/s^2, you can use the equation F = ma. Here, F represents force, m represents mass, and a represents acceleration. So, you can substitute the given values into the equation: F = (25 kg) * (20 m/s^2). Calculate this to find the force.
2. To find the acceleration of a mass when a force of 6 N acts upon it, you can use the same equation, F = ma. Given that the force is 6 N and the mass is 2 kg, substitute these values into the equation: 6 N = (2 kg) * a. Solve for a to find the acceleration.
3. To find the mass of a body when a force of 50 N gives it an acceleration of 10 m/s^2, once again you can use the equation F = ma. Now, the force is 50 N and the acceleration is 10 m/s^2. Substitute these values into the equation: 50 N = m * (10 m/s^2). Solve for m to find the mass.
4a. The weight of an object is the force with which it's attracted towards the center of the Earth. Weight is calculated using the equation W = mg, where W is weight, m is mass, and g is the acceleration due to gravity (which is approximately 9.8 m/s^2 on Earth). Substitute the given mass of 10 kg into the equation: W = (10 kg) * (9.8 m/s^2). Calculate this to find the weight.
4b. To find the mass of an object when given its weight of 490 N, you can rearrange the equation W = mg to solve for m. Divide both sides of the equation by g: m = W/g. Substitute the given weight of 490 N and the acceleration due to gravity of 9.8 m/s^2 into the equation: m = (490 N) / (9.8 m/s^2). Calculate this to find the mass.
Remember, these explanations provide you with the concepts and formulas to solve the problems. Make sure to substitute the provided values into the equations and calculate the answers accordingly. Good luck with your essay!
