Q9: It is observed that the time for the ball to strike the ground at B is 2.5 s. The speed va at which the ball was thrown is: 1.2m 50 m A. 20.5 m/s B. 45 m/s C. 78.6 m/s D. 10 m/s E. 32.4 m/s Q10: The truck travels along a circular road that has a radius of 50 m at a speed of 2 m/s. For a short distance when t 0, its speed is then increased by at (0.3t²) m/s², where t is in seconds. The speed of the %3D truck when t 3 sec is: %3D C. 36.4 m/s B. 28.4 m/s 18.4 m/s A. E. 4.7 m/s 50.2 m/s D.
