Answer:
10. m/s
Explanation:
Given:
y₀ = 3.1 m
y = 0 m
a = -9.8 m/s²
t = 2.4 s
Find: v₀
y = y₀ + v₀ t + ½ at²
0 m = 3.1 m + v₀ (2.4 s) + ½ (-9.8 m/s²) (2.4 s)²
v₀ = 10.47 m/s
Rounded to two significant figures, the student's initial velocity was 10. m/s.
Answer:
Diagram B because a plate resting on a table has gravity acting on it and normal/air resistance force working against the gravity with the same amount of force. Forces that are balanced don't move.
