Velocity = displacement / time
v = 6 / 3/4
v = 6*4/3
v = 24/3
v = 8 m/s toward north
In short, Your Answer would be 8 m/s north
Hope this helps!
Answer:110.25 m
Explanation:v^2 = u^2 + 2as
21^2 = 0 - 2*2*s
s = 441/4
s=110.25 m
Answer:
3600 J
Explanation:
Kinetic energy of an object is the energy posses by an object solely due to its motion.
It can also be defined as the amount of work that can be done when an moving object come to test.
Kinetic energy of an object can be calculated by the equation,
K.E. = ½mv²
Where m = mass, v = velocity
So you get,
K.E. = ½×0.5×(120)² = 3600 J
<h2><u>Question</u><u>:</u><u>-</u></h2>
Ryan applied a force of 10N and moved a book 30 cm in the direction of the force. How much was the work done by Ryan?
<h2><u>Answer:</u><u>-</u></h2>
<h3>Given,</h3>
=> Force applied by Ryan = 10N
=> Distance covered by the book after applying force = 30 cm
<h3>And,</h3>
30 cm = 0.3 m (distance)
<h3>So,</h3>
=> Work done = Force × Distance
=> 10 × 0.3
=> 3 Joules

Answer:
True
