Answer:2.103 m/s
Explanation:
Given
mass of sports car
mass of SUV
Suppose u is the velocity if sports car before collision
Conserving momentum we get
After collision the combined mass drag 2.8 m and finally stops
From work energy theorem work done by friction is equal to change in kinetic energy of the combined mass system
where
Initial velocity
Answer:
Ws=8.75 Watts
Explanation:
As per fig. of prob 02.061, it is clear that R5 and R4 are in parallel, its equivalent Resistance will be:
Now, this equivalent Req45 is in series with R3, therefore:
This Req345 is in parallel with R2, i.e
Now this gets in series with R1:
Now, the power delivered Ws is:
there are different types of power so ill show you all the examples of power.
Answer:
0.5N/kg
Explanation:
use formula:
F = m.a
500= 1000 × a (divide by 1000 on both sides)
0.5 =a
