A ball travels with velocity given by Error converting from MathML to accessible text., with wind blowing in the direction given
by Error converting from MathML to accessible text. with respect to some co-ordinate axes. What is the magnitude of the velocity of the ball in the direction of the wind
1 answer:
Answer: The magnitude of the velocity = 2/5 m/s
Explanation:
In this question, the magnitude of the velocity is the product of the magnitude of the displacement vector and the magnitude of the component of the velocity that acts in the direction of displacement.
This will be a scalar projection of V onto X

Answer: 17 m/s
Velocity and acceleration are vector quantities. Let leftwards be defines as negative and rightwards as positive direction.
It is given that canoe is drifting left with a velocity of
The canoe rider is moving towards right with a constant acceleration,
we need to find the velocity of canoe after 4 s.
we will use the equation of motion:
where, v is the final velocity, u is the initial velocity, a is the acceleration and t is the time.
Insert the values in the above equation:
Hence, velocity of canoe after 4 s would be 17 m/s.
