Answer:
c 275 m
Explanation:
Given parameters:
Final velocity = 73.5m/s
Unknown:
Height of fall = ?
Solution:
Since the body is falling from rest, U = 0 or initial velocity is 0m/s. Then we use one of the kinematics equation to solve this problem.
V² = U² + 2gH
V is the final velocity
U is the initial velocity
g is the acceleration due to gravity
H is the height
73.5² = 0² + (2 x 9.8 x h)
5402.25 = 19.6h
h = 275.6m
Answer:
It'd be frozen I think. either that or it'd be sucked out of oxygen
Explanation:
Explanation:
given: m= 105kg,f=170N,a=?
F = m×a
a = f/m
a=170/105
therefore, a=1.62m/s^2
We can solve this problem by conserving linear momentum.
We have then that:
P1 = P2
m1v1 + m2v2 = m1v1 '+ m2v2'
Substituting values and clearing:
95 (0) + 0.065 (0) = 95v + 0.065 (4)
0 = 96v + 0.26
96v = -0.26
v = -0.0027 m / s
The man moves in the opposite direction to the stone.
answer:
the speed that a man acquire as a result is v = -0.0027 m / s
