First of all, we need to convert the final angular velocity from rpm (revolutions per minute) to rad/s. Keeping in mind that
We have
the angular acceleration is given by
where
is the initial velocity (in this case, zero), and
is the time needed to accelerate the drill to its final velocity. Using
, we can calculate

Answer:
The error in tapping is ±0.02828 ft.
Explanation:
Given that,
Distance = 200 ft
Standard deviation = ±0.04 ft
Length = 100 ft
We need to calculate the number of observation
Using formula of number of observation
Put the value into the formula
We need to calculate the error in tapping
Using formula of error
Put the value into the formula
Hence, The error in tapping is ±0.02828 ft.
Answer:
a) 10.0 m/s
b) -4.68 m/s
Explanation:
Given:
y₀ = 0 m
y = 4.00 m
t = 1.50 s
a = -9.8 m/s²
Find: v₀, v
y = y₀ + v₀ t + ½ at²
4.00 = 0 + v₀ (1.50) + ½ (-9.8) (1.50)²
v₀ = 10.0 m/s
v = at + v₀
v = (-9.8) (1.50) + 10.0
v = -4.68 m/s
Answer:
40 m/s
Explanation:
If you multiply the acceleration with time you get the average speed.
