The position of the ball is given by the coordinates (x , y). The position of the ball depends on time t. The motion of the ball is defined by the motion functions: x(t) , y(t). Note that at time t = 0 , the ball is launched from the point (x , y) = (0 , yo) with the velocity vo. The initial velocity vector vo has magnitude vo and direction θo. The initial position of the ball will tell us how high the window is. From the y-axis on the graph we can see that the ball is \(\text{4}\) \(\text{m}\) from the ground. The window is therefore \(\text{4}\) \(\text{m}\) above the ground. Find the time taken to reach the maximum height. Q10.

- Suppose the ball in Figure 8.1 has an initial velocity v 0 and a mass m. If the spring constant is k, what is the maximum compression of the spring ? In the initial situation, the spring is in its relaxed position (U = 0). The total energy of the ball-spring system is given by. The maximum compression of the spring will occur when the ball is.
- Just think about throwing a ball against a solid wall. The harder you throw the ball against the wall, the harder it bounces back. That is the reason it is easier to hit a home run on a fastball than on a curveball. Conservation of momentum also means that the bat can transfer some of its momentum to the ball
- Section A Motion of a golf ball Suppose a golfer hits a ball with a velocity of 45 m s-1 at an angle of 20° to the horizontal. The projectile model can be used to answer some questions about what will happen to the ball later during its flight. Finding the position at a later time . Where will the ball be 2 seconds later? Horizontal motion.
- 3 Example 2: Find the velocity, acceleration, and speed of a particle given by the position function r(t) =2cost i +3sint j at t = 0.Sketch the path of the particle and draw the velocity and acceleration vectors for the specified value of t. Solution: We first calculate the velocity, speed, and acceleration formulas for an arbitrary value of t.In the process, we substitute and find each of.
- 12.3. The Calculus of Motion. A common use of vector-valued functions is to describe the motion of an object in the plane or in space. A position function →r(t) gives the position of an object at time t. This section explores how derivatives and integrals are used to study the motion described by such a function

Calculate the magnitude of change of momentum occurred in the motion of the hockey ball by the force applied by the hockey stick. Solution. Given, mass of the ball (m) = 200g. Initial velocity of the ball (u) = 10 m/s. Final velocity of the ball (v) = - 5m/s. Initial momentum of the ball = mu = 200g × 10 ms-1 = 2000 g.m.s- A steel ball of mass m1 = 0:9kg and a cord of length of L = 2m of negligible mass make up a simple pendulum that can pivot without friction about the point O, as in the gure below. This pendulum is released from rest in a horizontal position, and when the ball is at its lowest point it strikes a block of mass m2 = 0:9kg sitting at rest on a. A lead ball of mass 0.25 kg is swung round on the end of a string so that the ball moves in a horizontal circle of radius 1.5 m. The ball travels at a constant speed of 8.6 m s-1. (a)€€€€ (i)€€€€€€Calculate the angle, in degrees, through which the string turns in 0.40 s

The ball, m 1, and bat, m 2, both have initial velocities before the collision (subscript b), with the ball's velocity being negative. After the collision (subscript a) both bat and ball have positive velocities
