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.
Answer:
The correct solution is "15 kgm/s". A further explanation is given below.
Explanation:
The given values are:
Mass,
m = 5 kg
Velocity,
v = 3 m/s
By applying the formula of momentum, we get
⇒
On substituting the given values, we get
⇒
⇒
