Explanation:
KE is directly proportional to the square of velocity / speed.
if speed is 2 times (doubled) the KE will be
= 4 times the original KE
Answer:
a
The speed is
b
The distance is
Explanation:
From the question we are told that
The speed of the banana is
The distance from my location is
The time taken is
The speed of the ice cream is
substituting values
The distance of separation between i and Valdimir is the same as the distance covered by the banana
So
substituting values
Answer:
F = 0
Explanation:
The net force acting on an object is given by the product of mass and acceleration. We know that acceleration is equal to the rate of change of velocity.
Net force,
F = ma
The skier is traveling at a constant velocity, it means there is no change in velocity i.e. acceleration is equal to 0. Hence, the force on her is 0.
