Final answer:
To accurately calculate the force exerted by the truck on the car during the collision, we would need the acceleration of the truck.
Step-by-step explanation:
To find the force exerted by the truck on the car during the collision, we need to calculate the net force exerted on the car. According to Newton's second law, F = ma, where F is the force, m is the mass, and a is the acceleration. In this case, we are given the mass and acceleration of the truck. Using the given values, we can calculate the force exerted by the truck on the car during the collision.
The mass of the truck is 20 tons, which is equivalent to 40,000 lbs (1 ton = 2000 lbs). The acceleration of the truck is not given in the question. Therefore, we cannot calculate the force exerted by the truck on the car using the given information. We would need the acceleration of the truck during the collision to calculate the force accurately.
