You are lifting a 10 kg block straight up at a constant speed of 10 m/s. How much force are you exerting on the block?

The force exerted is

Explanation:

From the question we are told that

   The mass of the block is

    The speed is  

Generally the force exerted to lift the object at constant speed is equivalent to the wight of the ball, this is mathematically represented as

             Here  

=>    

=>    

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
