Explicacion
m = 65 kg
g = 10 m/s²
r = 0.5 cm (1m / 100 cm) = 0.05 m
A = π r² = π (0.05 m)² = 0.00785 m²
F =W = m g = 65 kg(10 m/s²) = 650 N
P = F/A = 650 N / 0.00785 m² = 82802.54 N/m²
Answer:
31.905 ft/s²
Explanation:
Given that
Mass of the pilot, m = 120 lb
Weight of the pilot, w = 119 lbf
Acceleration due to gravity, g = 32.05 ft/s²
Local acceleration of gravity of found by using the relation
Weight in lbf = Mass in lb * (local acceleration/32.174 lbft/s²)
119 = 120 * a/32. 174
119 * 32.174 = 120a
a = 3828.706 / 120
a = 31.905 ft/s²
Therefore, the local acceleration due to gravity at that elevation is 31.905 ft/s²
Answer:
It does not indicate the car's direction. Since velocity is both magnitude and direction, the speedometer measures speed but does NOT measure velocity
