Answer:
5.17
Explanation:
24.80/0.08 = 3.10
24.80/0.015 = 16.53
16.53 + 3.10 = 19.63
24.80 - 19.63 = 5.17

An object is moving due north at 32m/s. then this tells about the velocity of the object as it has the direction.
<h3>What is the difference between velocity and speed?</h3>
The immediate velocity of an item is then the value of its immediate pace. Speed tells you the way rapid. Velocity tells you the way rapid and in what route.
When you realize each velocity and route of an item's motion, you realize the speed of the item. Velocity tells us the velocity and route of a shifting item. Acceleration tells us the charge at which the pace changes.

The acceleration of the pendulum mass D is; r"_d =  [x''(t) + lθ'' cos θ - lθ'² sin θ]i - l[θ'' sin θ - θ'² cos θ]j
<h3>What is Kinematics of particles?</h3>
Kinematics is the study of the geometry of motion of particles, rigid bodies, etc., disregarding the forces associated with these motions. However, Kinematics of a particle is the motion of a point in space.
From the sample problem, we can solve it using the (x, y, z) coordinate system to get;
r_c = x(t) i
r_d = [x(t) + l sin θ]i + l cos θ j
Finding the first derivative of r_d gives velocity as;
r'_d =  [x'(t) + lθ' cos θ]i - lθ' sin θ j
Taking the second derivative of r_d gives the acceleration as;
r"_d =  [x''(t) + lθ'' cos θ - lθ'² sin θ]i - l[θ'' sin θ - θ'² cos θ]j
A sample problem of kinematics of particles is;
A block C slides along the horizontal rod, while a pendulum attached to the block can swing in the vertical plane. Find the acceleration of
the pendulum mass D.
