Calculation of Velocity Before Collision
To determine the velocity of the car just before it hits the ground, we can use the formula for velocity under free fall:
- **Formula:**
\( v = u + gt \)
Where:
- \( v \) = final velocity
- \( u \) = initial velocity (0 m/s, since the car is dropped)
- \( g \) = acceleration due to gravity (approximately \( 9.81 m/s^2 \))
- \( t \) = time of fall (1 second)
- **Calculation:**
- Since \( u = 0 \):
\( v = 0 + (9.81 \, \text{m/s}^2)(1 \, \text{s}) \)
\( v = 9.81 \, \text{m/s} \)
Force Applied Before Collision
Next, we can calculate the force applied just before the car collides with the ground using Newton's second law of motion:
- **Formula:**
\( F = ma \)
Where:
- \( F \) = force
- \( m \) = mass of the car (1200 kg)
- \( a \) = acceleration (in this case, it is \( g \), the acceleration due to gravity)
- **Calculation:**
- \( F = 1200 \, \text{kg} \times 9.81 \, \text{m/s}^2 \)
- \( F = 11772 \, \text{N} \)
Summary of Results
- **Velocity before collision:**
- \( 9.81 \, \text{m/s} \)
- **Force applied during the fall:**
- \( 11772 \, \text{N} \)
This provides a clear understanding of the car's velocity just before impact and the force exerted due to gravity.
