Question

A point mass of m = 3 kg is currently moving on a frictionless ground into the positive x-direction with constant speed vo =7 [m/s]. In an x-interval of 2 [m] lies ahead, there will be a chance to apply constant force (over the interval) on the mass to change its direction so that it will be launched with an angle of 45e to the ground after passing the interval.

 i. If the force can only be in the y-direction, what should the magnitude of the force be? (Don't forget gravity!) 

ii. Find the direction and the magnitude of the force when you want the launching speed to be the same as the traveling speed .
