-- The acceleration of gravity is 9.8 m/s².
So if there's no air resistance, the speed of a falling object
always increases by 9.8 m/s for every second it falls.
Speed = (original speed) + (gravity x falling time)
-- If it has no vertical speed when it started, then at the end
of 3 seconds, its speed is
= (0) + (9.8 m/s² x 3 sec)
Velocity = 29.4 m/s downward .
21N
Explanation:
Given parameters:
Mass of wagon = 14kg
Acceleration = 1.5m/s²
Unknown:
Net force on wagon = ?
Solution:
Force is a pull or push on a body that causes a body to change its state. It is expressed as:
Force = mass x acceleration
Force on wagon = 14 x 1.5 = 21N

Answer:
His first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. In other words its inertia.
