Question

You are speeding your 1500 kg truck down Ferguson on a Ferguson on a Friday night at 28 m/s. you see a squrirel in the road and slam on the brakes to avoid hitting it. the brakes plus the road friction generate 5000N of force on the car. What is the initial speed of the 1500 kg truck?

A) 28 m/s
B) 1500 kg
C) Ferguson
D) 5000 N

Answer 1

The initial speed of the truck is 28 m/s. This value is directly provided in the problem statement and is independent of the braking force applied later.

Step-by-step explanation:

The initial speed of the 1500 kg truck is given as 28 m/s. This is clearly stated in the problem description and is not affected by the subsequent events of the truck braking to avoid hitting a squirrel.

The force of 5000 N exerted by the brakes and road friction will determine how quickly the truck comes to a stop, but it does not change the initial speed.
