Hi, I really need some help on these homework problems. Sorry I couldnt paste the pictures in but please help me! 1) When a 58 gram ball is served, it accelerates from rest to a speed of 45 m/s. The impact with the racket gives the ball a constant acceleration over a distance of 44 cm. What is the magnitude of the average net force acting on the ball? 2) Only two forces act on an object (mass=4.0 kg). Find the magnitude and the direction (relative to the x-axis) of the acceleration of the object. The picture depicts a box with a central angle, the "y-axis" vector is 60.0 N and the "x-axis" vector is 40.0 N. 3) Two forces, F1 and F2, act on the 5.00 kg block. The magnitude of the forces are F1=45.0 N and F2=25.0 N. What is the horizontal acceleration (magnitude and direction) of the block. The picture depicts a box and on the upper left hand corner F1 vector is coming down, creating a 65° angle. F2 vector is going into the middle of the right side. 4) Only two forces act on an object (mass=3.00 kg). Find the magnitude and direction (relative to the x-axis) of the acceleration of the object. The picture depicts a box with 45° angle placed in the middle. The x vector is 40. 0 N and the y vector is 60.0 N.
