1. Oscar throws a ball toward a wall with a speed of 25 m/s at an angle of 40 degrees above ground. The wall is 22 m from the release point of the ball. a) How far above the release point does the ball hit the wall b) What is the magnitude and direction of the balls velocity as it hits the wall? c) When it hits the wall, has it passed the highest point on its trajectory? 2) A 2.00 kg block (mass t) and a 5.00 kg block (mass 2) are connected by a light string as shown in Figure 1 the inclination of the ramp is 40.0 degrees. The coefficient of kinetic friction between the block and the ramp is 0.25. What is (a) the acceleration of each block and (b) the tension in the string? 2 403) The massless spring of a spring gun has a force constant k='| 2 N/cm. When the gun is aimed vertically, a 15-g projectile is shot to a height of 5.0 m above the end of the expanded spring. (Figure 2) How much was the spring compressed initially? 'l ' Ill: ,1 l li'ill l
