Answer:
For question 1:
The force required to accelerate the car can be found using the formula: Force = mass x acceleration.
Given: Mass = 1300 kg, Acceleration = 4.0 m/s².
Force = 1300 kg x 4.0 m/s² = 5200 N.
For question 2:
The mass of the object can be calculated using the formula: Force = mass x acceleration.
Given: Force = 150 N, Acceleration = 6 m/s².
150 N = mass x 6 m/s²
Mass = 150 N / 6 m/s² = 25 kg
For question 3:
Using the same formula, Force = mass x acceleration.
Given: Mass = 50 kg, Acceleration = 2 m/s².
Force = 50 kg x 2 m/s² = 100 N.
For question 4:
Given: Mass = 642 kg, Acceleration = 13 m/s².
Force = 642 kg x 13 m/s² = 8346 N.
Therefore:
1. Force required to accelerate the car at a rate of 4.0 m/s² is 5200 N.
2. The mass of the object accelerating at 6 m/s² with a 150 N force is 25 kg.
3. Force needed to accelerate a 50 kg roller skater at 2 m/s² is 100 N.
4. The force required to accelerate a Formula 1 car weighing 642 kg at 13 m/s² is 8346 N.
