Answer:
The distance up to which they can jump is 1.5 m
Solution:
As per the question:
The extension of the legs, d = 0.600 m
Acceleration,
where
g = acceleration due to gravity =
Now,
Let the initial velocity of the jump be v m/s
So, by the third eqn of motion:
(1)
where
v' = final velocity
a = acceleration
d = distance between the legs
Also, for maximum range, angle,
(2)
x = maximum horizontal range
Thus, using eqn (1):
Now, using eqn (2):
Answer:
the work done by the person
the work done by gravuty
Explanation:
Because the velocity is constant the cyclist has to excert a force equal to the component of the weight.
The work done by the person is given by:
and the work done by the gravity:
