Explanation:
1) Acceleration is defined as the variation of Velocity in time :
(1)
A body also has acceleration when it changes its direction.
In this case we have a bus with a velocity of 60m/s to the east, that accelerates in a time 10s. So, we have to find the bus's acceleration:
(2)
(3) This is the bus's accelerration
2) Now we have a car that accelerates to the west in order to reach a speed of in the same direction, and we have to find the time it takes to the car to reach that velocity.
Therefore we have to find from (1):
(4)
(5)
Finally:

Answer:
(A⃗ ×B⃗ )⋅C⃗ = 69.868
Explanation:
We simplify the cross product first, thereafter the solution of the cross product is now simplified with the dot product as shown in the step by step calculation in the attachment
Answer:
Explanation:
Let +y is upward direction and backward be +x direction
then we have given data
From equation simple motion we find the time
So
To get the distance between the point the package ejected to the point it the ground.
Now we have to get the distance the helicopter travels during same interval
Now to get the distance between the package and helicopter when package hit the ground
0
Acceleration is the rate of change of speed and there’s no change
