Answer:
91 m
Explanation:
v₀ = 2.5 m/s
a = 4.2 m/s²
t = 6.0 s
Find: Δx
Δx = v₀ t + ½ at²
Δx = (2.5 m/s) (6.0 s) + ½ (4.2 m/s²) (6.0 s)²
Δx = 90.6 m
Rounded to the nearest whole number, the distance traveled is 91 m.
Answer:
B
Explanation:
Formula
Mechanical advantage = length of the ramp / height
Givens
Length of the ramp = 8
Mechanical advantage = 2
height = ?
Solution
2 = 8feet / height Multiply both sides by height
2* height = 8 feet * height / height Combine
2* height = 8 feet Divide by 2
2*height/2 = 8 feet/2
height = 4 feet.
