13:57 ..ooo AT&T; quest.cns.utexas.edu 012 (part 1 of 3) 10.0 points A 4.25 kg block slides down a smooth, fric- tionless plane having an inclination of 35 The acceleration of gravity is 9.8 m/s Find the acceleration of the block. Answer in units of m/s 013 (part 2 of 3) 10.0 points What is the block's speed when, starting from rest, it has traveled a distance of 2.3 m along the incline Answer in units of m/s. 014 (part 3 of 3) 10.0 points What is the magnitude of the perpendicular force that the block exerts on the surface of the plane at a distance of 2.3 m down the

Explanation / Answer

a=9.8 Sin35=5.62m/s2

v2=u2+2as

v2=02+2x 5.62 x 2.3

v=5.08m/s

FN=mgCos35=4.25x 9.8 Cos35=34.12N
