<span>Protein is the type of food which is retered to as the building block of human body. Other functions of protein includes: it is a component of every part of the body especsially the hairs and nails. The body uses it to build and repair tissues, Itis used by the body to produce enzymes, hormones and other body chemicals. It is also the building block for bones, muscels, cartilages, skin and blood.</span>
A particle moves along a straight line with equation of motion s = f(t), where s is measured in meters and t in seconds. Find the velocity and the speed when t = 4. f(t) = 12t² + 35 t + 1
Answer:
Velocity = 131 m/s
Speed = 131 m/s
Explanation:
Equation of motion, s = f(t) = 12t² + 35 t + 1
To get velocity of the particle, let us find the first derivative of s
v (t) = ds/dt = 24t + 35
At t = 4
v(4) = 24(4) + 35
v(4) = 131 m/s
Speed is the magnitude of velocity. Since the velocity is already positive, speed is also 131 m/s

Answer:
Explanation:
Given
Height of ceiling is 
Initial speed of Putty 
Speed of Putty just before it strike the ceiling is given by
where v=final velocity
u=initial velocity
a=acceleration
s=displacement
time taken by putty to reach the ceiling
