Answer:
Between the principal focus and the pole of the mirror
Answer:
The speed of the large cart after collision is 0.301 m/s.
Explanation:
Given that,
Mass of the cart, 
Initial speed of the cart, 
Mass of the larger cart, 
Initial speed of the larger cart, 
After the collision,
Final speed of the smaller cart,
(as its recolis)
To find,
The speed of the large cart after collision.
Solution,
Let
is the speed of the large cart after collision. It can be calculated using conservation of momentum as :





So, the speed of the large cart after collision is 0.301 m/s.
Answer:
B) 1/5 ba^2 T^5
Explanation:
The dissipated energy is given by the work done over the object by the force F=-bv. The work is given by the following formula:

you derivative the function f(x) and replace v by the derivative dx/dt you obtain:

hence, the dissipated energy is 1/5 ba^2 T^5
The answer is the diameter of the cam shaft.
This is used to compute for the area of the circle so you can multiply it with the rocker ratio to get maximum amount of weight the valve can lift.
Since the body is moving with uniform motion therefore the body doesn't accelerate
therefore acceleration is 0m/s^2
