Answer:
44 m
Explanation:
Given:
v₀ = 4.0 m/s
v = 18 m/s
t = 4.0 s
Find: Δx
Displacement is the average velocity times time:
Δx = ½ (v + v₀) t
Δx = ½ (18 m/s + 4.0 m/s) (4.0 s)
Δx = 44 m
Answer:
Radiation is transferred through electromagnetic waves so D.
Explanation:
U = 0, initial vertical velocity
v = 60 mph = 88 ft/s
Ignore air resistance and take g = 32 ft/s².
It t = time to attain 60 mph, then
(88 ft/s) = (32 ft/s²)*(t s)
t = 88/32 = 2.75 s
Answer: 2.75 s
