The above are questions related to the formula of force F = m * a i.e. mass * accleration. It is defined by the Newton's second law of motion.
In the attachment, I can see that Question 1) and Question 2) are already done, So lemme start from Question 3[tex])[/tex]
3) Provided:-
- Force applied = 7000 N
- On a ball of mass = 0.5 kg
To FinD:-
- Acceleration of the ball...?
By using formula,
⇛ F = ma
⇛ 7000 N = 0.5 kg × a
⇛ a = 7000 / 0.5 m/s²
⇛ a = 14000 m/s²
So, the ball acclerates at the rate of 14000 m/s².
4) Provided:-
- Accleration of the truck = 10 m/s²
- On a truck of mass = 31200 kg
To FinD:-
- Force applied on the truck..?
By using formula,
⇛ F = ma
⇛ F = 31200 kg × 10 m/s²
⇛ F = 312000 kg/m/s²
⇛ F = 312000 N
So, force on the truck = 312000 N
5) a) Force applied = 100 N
Mass applied = 5 kg
Then, Acceleration = 100 ÷ 5 = 20 m/s²
b) Force applied = 100 N
Mass applied = 10 kg
Then, Acceleration = 100 ÷ 10 = 10 m/s²
c) Force applied = 100 N
Mass applied = 20 kg
Then, Acceleration = 100 ÷ 20 = 5 m/s²
d) Force applied = 100 N
Mass applied = 50 kg
Then, Acceleration = 100 ÷ 5 = 2 m/s²
And we are done !!
