The magnitude of displacement is 8.6 km.
The direction of her displacement is north east.
Explanation:
Given that,
Christina drives his moped 7 kilometers North and stop for lunch and then drive 5 km east.
We need to calculate the total distance
Using formula of distance
Put the value into the formula
We need to calculate the magnitude of displacement
Using formula of displacement
The direction of her displacement is north east.
Hence, She covers the distance is 12 km.
The magnitude of displacement is 8.6 km.
The direction of her displacement is north east.
Answer:
The magnitude of the flux of electric field through a square of surface area is zero.
Explanation:
It is given that square box is parallel to yz-plane which has normal vector perpendicular to plane in x-direction. Angle between normal vector of area and electric field is 90°. Substituting in (1)
Answer:
a) -2.038 m/s²
b) 40.33 mph
c) 312.5 m
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
Acceleration of the boat is -2.083 m/s² if the boat will stop at 150 m.
Speed of the boat by when it will hit the dock is 18.03 m/s
Converting to mph
Speed of the boat by when it will hit the dock is 40.33 mph
The distance at which the boat will have to start decelerating is 312.5 m
