Question

Using second law of motion, derive the relation between force and
acceleration. A bullet of 10 g strikes a sand-bag at a speed of 103 m s-1 and
gets embedded after travelling 5 cm. Calculate
(i) the resistive force exerted by the sand on the bullet
(ii) the time taken by the bullet to come to rest.

Answer 2

Answer:

SECOND LAW OF MOTION

Explanation:

• Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects is called heat.
