Using the kinematic equation:
Vf=Vi+at then plug the values in.
Vi=0 m/s (Because the ball is dropped)
t=3 s.
a=9.81 m/s=g
Vf=0+3*9.81;
Vf=29.43 m/s
Speed and velocity have the same magnitudes. The only difference is that speed is a scalar quantity and velocity is a vector quantity. In other words, speed is just a magnitude, while velocity is a magnitude with direction. They're essentially the same.
Let's convert miles to meters and minutes to seconds
1/4 mile = 402.34 meters ( 1 mile = 1609 m)
13.1 minutes = 786 seconds (1 minute = 60 seconds)
Speed is calculated as distance over time, thus,
Speed = (402.34 meters)*8/786 seconds
a.) Speed = 4.1 m./s
b.) Velocity = 4.1 m/s
<span> <span> The answer to your question is: increase the force applied to the object.
Two items are provided as a basis for that conclusion:
1. According to Newton's Second Law of Motion, the formula for finding force is: F = ma
where F is the force,
m is the mass of an object,
and a is the acceleration of the object.
And 2: work = force x distance or W = F x d.</span></span>
Answer:
A derived quantities is terms of the 7 base quantities via a system of quantity equations which are called SI derived units.
