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?
I am not a physicist; however, I believe you can work all of your problems, as DrWLS suggested, with F=ma.
physics- drbob can u plz help me??? -
since force is equal to mass × acceleration now question one answer is 25×20=500
