If the object is following a curve, or turning a corner, or slowing down, or speeding up, then it's motion is accelerated.
Answer:
v = 10 m/s
Explanation:
Given,
Length of the vine, l = 36 m
Angle of inclination = 31.0◦ with the vertical
acceleration due to gravity = 9.81 m/s²
Using Conservation of energy
KE = PE




v = 10 m/s
Hence, the speed of the swing is equal to 10 m/s
We have that the see-saw will be balance if a weight of
is added to Nural's side of the see-saw

From the Question we are told that
Wan’s mass is 
Nurul’s mass is 
Generally
The Will be balance when the weight on both sides of the see-saw are equal




In conclusion
The see-saw will be balance if a weight of
is added to Nural's side of the see-saw

Answer:
the pencil i have on my desk is hard
Explanation:
i dont have 5 but here is one
Answer:
25.2 km east
Explanation:
The relationship between velocity and displacement is given by:

where
v is the velocity
d is the displacement
t is the time
In this problem, we have:
east is Rebecca's velocity
is the time taken
Re-arranging the equation, we can find Rebecca's displacement:

and the direction is same as velocity (east)
