2) The figure shows two forces that act on a 4.0 kg block as the block slides through a rightward displacement of d = 6 m: F2 =12 N, 0 =60, F1 =20 N. At the start of the displacement, the block kinetic energy of 22 J. What is the block's speed (m/s) at the end of the displacement? D a) 3.3 b) 7.3 C) 4.9 d) 2.5 e) 9.4 f) 8.5 Schlitt g) 4.2 h) 5.2 i) 6.3 j) 5.6
