Answer:
Impulse in the first collision is greater
Explanation:
u = Initial velocity of cart
v = Final velocity of cart
m = Mass of of cart
First collision
Impulse

Second collision
Impulse

Hence, the impulse in the first collision is greater than the second impact
THE answer the table is holding the book up would be a normal force
Answer:
3469.788 m
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
First rocket

Second rocket

When this will collide the total distance they would have covered would be 6000 m.


Hence at 13.72 seconds they will collide assuming they are launched at the same time.

The second rocket would have gone 3469.788 m when they collide
Answer:
