Answer:
1.315 m
Explanation:
Assumption: there is no resistance of any type
v= 5.08 m/s
g = 9.81m/s^2
change in kinetic energy = change in gravitational potential energy
mass on both side is same so it cancels out
and also making 'h' alone on one side
h= ((5.08)^2)/(2*9.81)
h =1.3153m
A material is said to be ductile if it can be stretched thin when tensile stress is administered. Such a material can be stretched into a wire.
This is different from malleability which describes a material that can bend or alter shape using compressive force e.g. hammering , rather than tensile stress.
Tensile stress is a type of force or stress that alters the length of a material in the same direction as the force being applied.
The opposite of ductile is brittle. Brittle materials can break when subjected too much tensile stress.
Answer: 55.0066 miles per hour
Explanation: i hope this helped, and pls mark me as brainliest
Answer:
Forward
Explanation:
Since the skier pushes himself along the snow on flat ground and he feels air resistance, he will only feels air resistance when he starts moving (unless wind is blowing in opposite direction). The net force vector is dependent on the amount of force applied by the skier here we assume that skier continues to move in forward direction. The net force vector will act in the direction of acceleration, since the skier continues to move in the forward direction, therefore the net force vector will also point in the forward direction.
