Explanation:
Mass of the ball, m = 0.058 kg
Initial speed of the ball, u = 11 m/s
Final speed of the ball, v = -11 m/s (negative as it rebounds)
Time, t = 2.1 s
(a) Let F is the average force exerted on the wall. It is given by :
F = 0.607 N
(b) Area of wall,
Let P is the average pressure on that area. It is given by :
P = 0.202 Pa
Hence, this is the required solution.
Answer:
The y-component of the car's position vector is 670m/s.
The x-component of the acceleration vector is -3, and the y-component is 40.
Explanation:
The displacement vector of the car with velocity
is the integral of the velocity.
Integrating we get the displacement vector
:
Now if the initial position if the car is
then the displacement of the car at time is
Now at , we have
The y-component of the car's position vector is 670m/s.
The acceleration vector is the derivative of the velocity vector:
and at it is
The x-component of the acceleration vector is -3, and the y-component is 40.
