It's easy to roll the the basket ball than bowling ball
It is because bowling ball is solid spherical ball which will have less moment of inertia
its moment of inertia is given as
While for the hollow ball like basketball we know that moment of inertia is given as
so here we can see for the same mass if we take basketball then its moment of inertia is more so it is easy to roll basket ball then to roll bowling ball.
So it is easy to roll basket ball then rolling ball
Answer:
Explanation:
Let the shells speed with respect to ground be
Let the shells speed with respect to ground be
mass of shell,
mass of gun,
The relative velocity of shell with respect to a free unconstrained gun,
According to the Newton's third law of motion the direction of the velocity of gun and shell will be in the opposite direction.
So, the relation between the relative velocity and their individual velocity will be:
......................(1)
<u>And according to the conservation of momentum (as the condition is very close to the elastic collision):</u>
substitute the value of from equation (1)
