Answer: 0.25m/s2
Explanation:
Acceleration is change in velocity with time
V = final velocity = 5m/s
U =Initial velocity = 3m/s
t = time = 8s
a = Acceleration =?
a = V — U / t
a = (5 — 3) / 8
a = 2/8
a = 0.25m/s2
Is this a real question? It’s B
It is know as the normal force.
When a solid is placed on a support, the latter exerts forces on the solid at each point of contact. These are forces that oppose the weight and prevent an object from falling.
This force is usually vertical and upward and often offsets the weight. If the solid is in equilibrium on the support the forces compensate the weight of the solid.
