A 1000 kg car pushes a 2000 kg truck that has a dead battery. When the drive steps on the accelerator, the drive wheels of the car push against the ground with a force of 4500 N.
a) What is the magnitude of the force of the car on the truck?
b) what is the magnitude of the force of the truck on the car?
a) 4500 N = (1000 + 2000) a
Solve for a.
a = 1.5 m/s^2
F(car on truck) = Mtruck* a = 3000 N
F(car on truck) = 2000 kg*1.5 m/s^2
= 3000 N
b) Because of Newton's third law, the answers to a) and b) are the same.
a) 4500 N = (1000 + 2000) a
Solve for a.
a = 1.5 m/s^2
F(car on truck) = Mtruck* a = 3000 N
F(car on truck) = 2000 kg*1.5 m/s^2
= 3000 N
b) Because of Newton's third law, the answers to a) and b) are the same.
a) The magnitude of the force of the car on the truck can be calculated using Newton's third law of motion, which states that every action has an equal and opposite reaction. Since the force pushing against the ground is 4500 N, the magnitude of the force of the car on the truck is also 4500 N.
b) Similarly, using Newton's third law of motion, the magnitude of the force of the truck on the car is also 4500 N. So, it seems like they are pushing each other with the same force. It's like they're playing a tug of war, but instead of a rope, they're using good ol' physics!
To determine the magnitude of the force of the car on the truck and the magnitude of the force of the truck on the car, we can use Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
a) The magnitude of the force of the car on the truck is the same as the force with which the car pushes against the ground, which is given as 4500 N. This is because, according to Newton's third law, the force exerted by the ground on the car is equal in magnitude but in the opposite direction.
b) Following Newton's third law, the magnitude of the force of the truck on the car is also 4500 N. This is because the force of the car on the truck and the force of the truck on the car are equal and opposite to each other.
Therefore, the magnitude of the force of the car on the truck is 4500 N, and the magnitude of the force of the truck on the car is also 4500 N.
