As per above given data
initial velocity = 19.3 km/s
final velocity = - 18.8 km/s
now in order to find the change in velocity
Part b)
Now we need to find acceleration
acceleration is given by formula
given that
now the acceleration is given as
so above is the acceleration
Answer:
Explanation:
Check attachment for solution.
Generally the movement of the knight is L, i.e (2,1), (1,2),(-1,2),(1,-2) etc.
So using Pythagoras theorem
x^2+y^2=1^2+2^2
x^2+y^2=5
Then, the knight will make one movement when the displacement is √5.
So let take a look at other positions
(1,0),(0,1),(-1,0), (0,-1).
Then, for us to have this kind of movement, the knight has to make 3 movements.
When the displacement is 1, then it will make 3 movement.
Let examine other positions
(2,2) or(-2,-2) or (2,-2) or (-2,2)
When the displacement is √8
Then, the movement of the knight is 4.
Let examine other points
(2,0) or (0,2) or (-2,0) or (0,-2)
When the displacement is 2.
The knight make 2 movement
Answer:
Impulse will be 12 kgm/sec
So option (b) will be correct option
Explanation:
We have given mass of the baseball m = 0.15 kg
Ball speed before hit
Ball speed after hitting ( negative direction due to opposite direction )
We have to find the impulse
We know that impulse is equal; to the change in momentum
So change in momentum =
So option (b) will be correct option
