Question

A 7 ton utility truck comes over a blind hill and cannot stop when he sees an obsticle in the road. He travels to the left of the road across 127 feet of dry, grassy ditch, 75 feet of dry pavement, and 81 feet of deep clay. He hits a tree on his right hand bumper at 227 feet, totalling his truck, and then continues to travel an additional 57 feet through brush, and pulverizing a steel and metal mesh fence.

How fast was the truck traveling?

Answer 1

80 mph using speed = mass / distance

Step-by-step explanation:

truck traveled = 227 feet + 57 feet

truck traveled = 284 feet

truck weighs 7 tons

truck weighs 15,422 pounds

formula to calculate the speed of the truck =

speed = mass / distance

mass is 15,422 pounds

distance is 284 feet

speed = 15,422 pounds / 284 feet

speed = 54.1 feet per second

convert feet per second to miles per hour by multiplying by 1.4667.

speed = 54.1 feet per second * 1.4667

speed = 80.0 miles per hour
