Explanation:
Answer:
6.13 s
219 N
Explanation:
Newton's law in the x direction:
∑F = ma
150 cos 30° N − 50 N = (30 kg) a
a = 2.66 m/s²
Δx = v₀ t + ½ at²
(50 m) = (0 m/s) t + ½ (2.66 m/s²) t²
t = 6.13 s
Newton's law in the y direction:
∑F = ma
Fn + 150 sin 30° N − (30 kg) (9.8 m/s²) = 0
Fn = 219 N
Answer:
The acceleration at lowest point is 19.62 m/s^2
Explanation:
Conservation of energy is an concept in which it is stated that the energy of an isolated object remains the same. Energy changes from one form to another.
Lets Assume
Constant of string is K
By using the conservation of energy we will have the following equation
1/2 x 80^2 x K = m x 9.81 x 120
3200 K = 1177.2 m
K = 1177.2 m / 3200
K = 0.368 m
At the lowest point we will have
a = ( K x X - m x g ) / m
a = ( 0.368 m x 80 - m x 9.81 ) / m
a = 19.62 m / s^2
So, the acceleration at lowest point is 19.62 m/s^2
Answer:
(a). The distance from the initial position is 6.68 km.
(b). The magnitude of their displacement is 7.05 km.
Explanation:
Given that,
Geese fly 4.0 km due west, then turn to north by 40° and fly another 3.5 km.
(a). We need to calculate the distance from the initial position
Using formula of distance
Put the value into the formula
(b). We need to calculate the magnitude of their displacement
Using formula of displacement
Hence, (a). The distance from the initial position is 6.68 km.
(b). The magnitude of their displacement is 7.05 km.
