1) Suppose a soccer player kicks the ball from a distance 30 m toward the goal. Find the initial speed of the ball if it just passes over the goal, 2.4 m above the ground, given the initial direction to be 40 above the horizontal.

2) An object of mass 0.69 kg is initially at rest. When a force acts on it for 2.9 ms it acquires a speed of 10.6 m/s. Find the magnitude (in N) of the average force acting on the object during the 2.9 ms time interval. (Enter a number.) N
