10. Myoe wants to increase her upper body strength by doing push ups She does one push up by applying a force of 10 N to carse her center of gravity 2 in How many punh ups must Jince compete to dd of work? 15 punh ups 10 push-ups 5 push-ups 20 punh-ups

## Step 1<br />The problem involves the concept of work done in physics. The formula for work done is given by:<br />### **Work = Force x Distance**<br />In this case, the force applied is 10 N and the distance is 2 m.<br /><br />## Step 2<br />Substitute the given values into the formula to calculate the work done in one push-up.<br />### **Work = 10 N x 2 m = 20 Joules**<br /><br />## Step 3<br />The problem asks for the number of push-ups required to do 100 Joules of work. To find this, we divide the total work by the work done in one push-up.<br />### **Number of push-ups = Total Work / Work done in one push-up = 100 Joules / 20 Joules/push-up = 5 push-ups**
