Answer:
let us use the expression v = ./2gS in both the cases.
a) In the first case g = 9.8 m/s^2 and S = 10.3 m.
So v = 14.21 m/s
b) in the second case, g = 1.64 m/s^2 and S = 4.2 m = 3.71 m/s

Answer:
1. it helps to change the direction.
2. it helps us to walk on ground.
3. it helps the vechils to break while moving.
4. helps in changing one form of enegry to another form. eg when we rub our hands we feel heat energy.
5. it opposites the force.
6. it helps us to change shape of objects.eg we roll the dough to make it roti.
7. it changes the state of body from rest motion.eg when we push any obj from inclined plane it moves.
i all know is just 7..
Answer:
a. Object 1 exerts a 10 newton force on object 2 in the direction of its 1 meter displacement.
Explanation:
Well, according to Newton’s second law of motion, the formula he had devised would be
Fnet = m • a
N = kg • m/s^2
In terms of mass and acceleration, it would be that 1 N = 1 (kg•m/s^2).
