Answer:
I believe it might be point A since the question ask what will result in the ln a largest increase in potential energy
Explanation:
Trust me, i'm a k12 student and its motor
Explanation:
It is given that,
Mass of the car 1,
Initial speed of car 1, (east)
Mass of the car 2,
Initial speed of car 2, (north)
(b) As the cars stick together. It is a case of inelastic collision. Let V is the common speed after the collision. Using the conservation of momentum as :
The magnitude of speed,
V = 12.22 m/s
(b) Let is the direction the wreckage move just after the collision. It is given by :
Hence, this is the required solution.
Answer:
14 m/s
Explanation:
The motion of the stone is a free fall motion, so an accelerated motion with constant acceleration g = 9.8 m/s^2 towards the ground. So, we can use the following SUVAT equation:
where
v is the final speed of the stone as it reaches the water
u = 0 is the initial speed
g = 9.8 m/s^2 is the acceleration
h = 10 m is the distance covered by the stone
Solving for v, we find
