Answer:
B) You should catch the ball.
Explanation:
In order to minimize the speed on the skateboard, you should catch the ball.
Let 'M' be the mass of the ball, 'm' the mass of the skater, 'V0' the speed the ball was thrown and 'Vs' the speed of the skater.
By conservation of momentum, if the skater catches the ball:
If the skater deflects the ball, it will assume a new velocity with direction opposite to that of the skater, let it be 'Vb':
Since:
A lower velocity would be achieved by catching the ball.
Answer:
Explanation:Explanation: Newton's 2nd law states acceleration is proportional to the net force acting on an object. ... This means if friction is present, it counteracts and cancels some of the force causing the motion (if the object is being accelerated). That means a reduced net force and a smaller acceleration
direction of the object's velocity
Answer:
Flooding of roads near the coast
Explanation:
-Storms surges have the potential to harm lives and property via storm surge, heavy rain or snow causing flooding or road impassibility, lightning, wildfires, and vertical wind shear.
-The significantly high amounts of rainfall during storms leads to flooding of coastal regions , roads included thus rendering them impassable.
