Answer:
8437.5
Explanation:
By applying the formula of kinetic energy:
Kinetic energy=1/2 mv^2
5.52 × 10 to the 5th power (100000) . In scientific notation you need to have a decimal numver times 10 to the power of something so you can divide 552000 by 10 5 times. So in order to get 552000 you need to have 10 to the 4th power and 5.52
Answer:
How does newtons first two laws of motion apply to the toy car?
Explanation:
For this question, we use the Coulumb's law to calculate the force on each particles. In this law, force between point charges are said to be proportional to product of each charge and is indirectly proportional to the distance of both charges. We do as follows:
F= kq(1)q(2)/d^2
= (9x10^9).(1.41 x 10^-5 C).(-<span>1.41 x 10^-5 C</span><span>)/.44^2
</span> = 4.067 N
Answer:
Explanation:
Given
mass of block is m
inclination of ramp is 
Initial kinetic energy 
Length of ramp is L
Block move a distance of L so it moves a vertical distance of 
Applying work Energy theorem i.e. change in kinetic energy of object is equal to work done by all the forces
Initial kinetic energy 
Final kinetic energy
