ACTIVITY #1 1. The mass of a large car is 1300 kg. How much force would be required to accelerate the car at a rate of 4.0m/sec²? 2. A force of 150 N is applied to an object that accelerates at a rate of 6 m/sec". What is the mass of the object? 3. How much force is needed to accelerate a 50 kg roller skater at 2 m/sec²? 4. What force is required, to accelerate a formula 1 car weighing 642kg at 13m/s²?​

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.
