Answer:
17 m
Explanation:
Draw a free body diagram. There are 3 forces on the block:
Weight force mg pulling down,
Normal force N pushing up,
and applied force F pushing right.
Sum of forces in the x direction:
∑F = ma
15 N = (5.1 kg) a
a = 2.94 m/s²
Given:
u = 0 m/s
v = 10 m/s
a = 2.94 m/s²
Find: s
v² = u² + 2as
(10 m/s)² = (0 m/s)² + 2 (2.94 m/s²) s
s = 17 m
