This is because of something called moments,
moment is the turning Effect of a force.
it is calculated by
moment=force×perpendicular distance from the line of action.
So if there is more distance from pivot the more the moment is for the same force.
Answer:
P=mv 2250*25=56250
Explanation:
p of truck =2250*25 =56250
since p of truck = p of car
then p of car = 56250
therefore p of car = 1210 * v
or, 56520=1210v
or,v= 56520/1210=46.48
so, v of car is 46.48m/s
Answer:
The average power the student expended to overcome gravity is 560W, Watts is a units of work it is Joules /time or kg*/
Explanation:
Weight = 700N
The power is the work in (Joules) or (N*m) in a determinate time (s) to get Watts (W) units for work
Answer:
formula: A mass m suspended by a wire of length L is a simple pendulum and undergoes simple harmonic motion for amplitudes less than about 15º. The period of a simple pendulum is T=2π√Lg T = 2 π L g , where L is the length of the string and g is the acceleration due to gravity.
