Answer:
Explanation:
It is given that,
Mass of lump, m₁ = 0.05 kg
Initial speed of lump, u₁ = 12 m/s
Mass of the cart, m₂ = 0.15 kg
Initial speed of the cart, u₂ = 0
The lump of clay sticks to the cart as it is a case of inelastic collision. Let v is the speed of the cart and the clay after the collision. As the momentum is conserved in inelastic collision. So,
v = 3 m/s
So, the speed of the cart and the clay after the collision is 3 m/s. Hence, this is the required solution.
Answer:
Banked
Explanation:
Banked curves are formed when the inner edge is below the outer edge.
It is done in order to ensure the reliability of the frictional force as it varies when the road is wet wet or oily. Thus in order to avoid these problems the curved roads are banked.
Banking of the curve provides the necessary centripetal force, i.e., the horizontal component of the normal reaction force to keep the vehicle i motion and thus helps in reducing the effect of the forward motion force on the vehicle.
Answer: It encourages scientists to give convincing evidence for the results
