Total mechanical energy = kinetic energy + potential energy
E = KE + PE
E = ½mv² + mgh
E = ½(0.1 kg)(2 m/s)² + (0.1 kg)(9.8 m/s²)(1.5 m)
E = 0.2 J + 1.47 J
E = 1.67 J
        
                    
             
        
        
        
We know, momentum = mass * speed
25kgm/s = 2 kg * s
s = 25/2 = 12.5 m/s
 
        
                    
             
        
        
        
The physical activity that a global positioning system resource can help me with is : ( A )  Hiking 
<h3>Function of Global positioning system ( GPS ) </h3>
GPS helps with the accurate measurement of physical activities  and factors such as location, time, elevation and so on. When hiking, the time, distance covered and location of the hiker  can be accurately measured with the use of the GPS. 
Hence we can conclude that The physical activity that a global positioning system resource can help me with is  Hiking.
