Wave base is the most affected by a wave in deep water. :]
Answer:
3.416 m/s
Explanation:
Given that:
mass of cannonball
= 72.0 kg
mass of performer
= 65.0 kg
The horizontal component of the ball initially
= 6.50 m/s
the final velocity of the combined system v = ????
By applying the linear momentum of conservation:




v = 3.416 m/s
Answer:
22600 cm³ (3 s.f.)
Explanation:
Please see the attached picture for the full solution.
Answer:
-
Explanation:
We are given that
Mass of cars= m=1900 kg
Initial speed of car=u=20 m/s
Final speed of car=v=0
Time=
=1.3 s
We have to find the average force exerted on the car.
Average force=



Hence, the average force exerted on the car that hits a line of water barrels=-
