Answer 1

• 2. 30N

• 3. 5,000N

• 4. 15 kg

• 5. 2,800 kg

Step-by-step explanation:

2. A 10 kg bowling ball would require what force to accelerate down an alleyway at a rate of 3m/s² ?

Notice that I completed the question with the garbled and missing values:

Data:

• F = ?

• m = 10 kg

• a = 3m/s²

Physical principles:

• Newton's second law:
  `F=m* a`

Solution:

• Substitute and compute

`F=10kg* 3m/s^2=30N`

3. Salty has a car that accelerates at 5 m/s². If the car has a mass of 1000 kg, how much force does the car produce?

Notice that I arranged the typos.

Data:

• F = ?

• m = ?

• a = ?

Physical principles:

• Newton's second law:
  `F=m* a`

Solution:

• Substitute and compute

`F=1,000kg*5m/s^2=5,000N`

4. What is the mass of a falling rock if it produces a force of 147 N?

Data:

• F = 147N

• m = ?

• a = falling rock

Physical principles:

• neglecting air resistance ⇒ a = g: gravitational acceleration: 9.8m/s²

• Newton's second law:
  `F=m* a`

Solution:

• Clear m from Newton's second law

`m=(F)/(a)`

• Substitute with F = 147 N and a = g = 9.8m/s², and compute

`m=(147N)/(9.8m/s^2)=15Kg`

5. What is the mass of a truck if it produces a force of 14,000 N while accelerating at a rate of 5 m/s²?

Data:

• F= 14,000N

• m = ?

• a =​ 5m/s²

Physical principles:

• Second Newton's law:
  `F=m* a`

Solution:

• Clear m from Newton's second law

`m=(F)/(a)`

• Substitute with F = 14,000 N and a = 5m/s², and compute

`m=(14,000N)/(5m/s^2)=2,800kg`
