No answer is possible, because you denied us the opportunity
to use any of the information in the picture.
Av Speed = total distance / time time = 32+ 46 / 2.7 = 28 m/sec
Av velocity = total displacement / time total = S / t
S = sqrt( 32^2 +46^2) = 56 m
Av Velocity = 56/ 2,7 = 20.75 m/sec
with angle tan^-1 = 0.7 north west ( about 35 degrees north west)
Answer:
2.29m
Explanation:
Given parameters:
Mass of the coconut = 1.4kg
Final velocity = 6.7m/s
Initial velocity = 0m/s
Unknown:
Height of the coconut initially = ?
Solution:
To solve this problem, we use one of the kinematics equation. The one given below is the best one to use.
V² = U² + 2gH
V is the final velocity
U is the initial velocity
g is the acceleration due to gravity
H is the height
So;
6.7² = 0² + (2 x 9.8 x h)
44.89 = 19.6h
h = 2.29m
Answer:
Conditions under which the belt and pulleys are operating – The friction between the belt and pulley may decrease substantially if the belt happens to be muddy or wet, as it may act as a lubricant between the surfaces.
