Answer:
Explanation:
From the given information:
the car's momentum = momentum of the truck
∴
(a) 816 kg × v = 2650 kg × 16.0 km/h
v = (2650 kg × 16.0 km/h) /  816 kg
v = 51.96 km/hr
(b) 816 kg × v = 9080 kg × 16.0 km/h
v = (9080 kg × 16.0 km/h) /  816 kg
v = 178.04 km/hr
 
        
             
        
        
        
Answer:
1047 miles
Explanation:
The radius of the Earth is
 (miles)
 (miles)
So its circumference, which is the total length of the equator, is given by

Now we know that the Earth rotates once every 24 hours. So the distance through which the equator moves in one hour is equal to its total length divided by the number of hours, 24:
