Answer:
Work done by the frictional force is 
Explanation:
It is given that,
Mass of the car, m = 1000 kg
Initial velocity of car, u = 26.1 m/s
Finally, it comes to rest, v = 0
We have to find the work done by the frictional forces. Work done is equal to the change in kinetic energy as per work - energy theorem i.e.
W = −340605 J
or
Hence, the correct option is (a).
Answer:
the net force applied to an object is directly proportional to the acceleration undergone by that object
Explanation:
This verbal statement can be expressed in equation form as follows:
a = Fnet / m
True, due to the amount of children being born is greater than that of people dying
The correct answer is B. wrap more coils of wire around the nail. This is how you can increase its magnetic strength. Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.
Answer:250.03m
Explanation:
Initial velocity =u=51mph
Angle=β=37
Acceleration due to gravity=g=10
The distance covered by the football is the range
Range=(u^2xsin2β)/g
Range=(51^2xsin(2x37))/10
Range=(51x51xsin74)/10
Range=(2601xsin74)/10
Range=(2601x0.9613)/10
Range=(2500.3)/10
Range=250.03m
