Answer:
30 m/s
Explanation:
Vf = ?
Vi = 0 m/s
a = 20 m/s^2
t = 1.5 s
Plug those values into the equation: Vf = Vi + at
Vf = 0 + (20)(1.5)
Vf = 30 m/s
 
        
             
        
        
        
Answer:
See a tractor is more slow but has a greater force and a car is fast but has a slower force
Explanation:
so your answer is Tractors have more force then cars
 
        
             
        
        
        
Answer:
The child will take 5.952 seconds to travel from the top of the hill to the bottom. 
Explanation:
Given that the child accelerates uniformly and that both initial ( ) and final speeds (
) and final speeds ( ), measured in meters per second, and acceleration (
), measured in meters per second, and acceleration ( ), measured in meters per square second, are known, we proceed to use the following kinematic equation to determine the time taken to travel from the top of the hill to the bottom (
), measured in meters per square second, are known, we proceed to use the following kinematic equation to determine the time taken to travel from the top of the hill to the bottom ( ), measured in seconds, is:
), measured in seconds, is:
 (1)
 (1)
If we know that  ,
,  and
 and  , then the time taken is:
, then the time taken is:

Answer:
P = 10 kPa
Explanation:
Given that,
The mass of a small table, m = 4 kg
The area of each leg = 0.001 m²
We need to find the pressure exerted by the table on the floor. Pressure is equal to the force per unit area. So

So, the required pressure is 10 kPa.
