Give one example of any basic physical system that shows simple harmonic motion and state the factors or variables in your example that would affect the frequency and amplitude of the motion.

An automobile and a truck start from rest at the same instant,with the automobile initially at some distance behind the truck.The truck has a constant acceleration of 2.20m/s2,and the automobile has an acceleration of 3.50m/s2.The automobile overtakes the truck after truck has moved 60.0m.
a)How much time does it take the automobile to overtake the truck?
b)How far the automobile behind the truck initially?
c)What is the velocity of each when they are next to each other?.

two balls of different masses are thrown vertically upward with same initial velocity .calculate the ratio of ratio of maximum height attained by them

a car changes its speed from 60 m/s to 40 m/s it does this at a rat of four seconds what was the acceleration of the car

a 3000 kg cannon fires a 10kg cannon ball the cannon recoils backwards at a speed of 5m/s how fast is the cannon ball traveling

If the coefficient of static friction is 0.35 and the normal force is 80 newtons, what is the maximum frictional force of the surface acting on the object?

Hi I have a question for my physics' homework!
It's about projectile.
Here is the question:
A projectile is launched from a height of 20 m with a velocity oriented 30 degrees above the horizontal. If the height reached is 45m, what is the initial velocity of the shot?

Thank you
