Answer: A 2m/s^2
Steps: Formula for acceleration. (Velocity Final - Initial Velocity) / Time
(24 - 0) / 12 = 2
        
             
        
        
        
Answer:
85.5 km/h 
Explanation:
 = time interval for first phase = 14 min =
 = time interval for first phase = 14 min =  h = 0.233 h
 h = 0.233 h 
 = time interval for second phase = 46 min =
 = time interval for second phase = 46 min =  h = 0.767 h
 h = 0.767 h 
 = average speed for the entire trip = 74 km/h
 = average speed for the entire trip = 74 km/h
 = average speed in first phase = 36 km/h
 = average speed in first phase = 36 km/h
 = average speed in second phase
 = average speed in second phase 
 = distance traveled in first phase
 = distance traveled in first phase 
 = distance traveled in first phase
 = distance traveled in first phase 
average speed is given as 




 km/h

Answer:
the group of units suggested by the international convention of scientists in 1960 AD to make similarties in meseurment all over the world is called SI units
 
        
             
        
        
        
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
