physics
how to solve for velocity using these values... distance time(s) 28.5 (initial) 4.26 (initial) 89 (final) 6.77 (final)

physics
the car travels at 20m/s when the driver sees a child. It takes 0.8s to react, then steps on the brakes and slows at 7.0m/s^2. How far does the car go before it stops?

physics
a bike first accelerates from 0m/s to 5.0m/s in 4.55, then continues at this constant speed for another 4.5s. what is the total distance traveled by the bike?

physics
a student drops a ball from a window 3.5m above the sidewalk. the ball accelerates at 9.80m/s^2. How fast is it moving when it hits the sidewalk.

physics
A bike accelerates from 0.0m/s to 4.0m/s in 4s. what distance does it travel?

Statistics
An automatic machine in a manufacturing process is operating properly if the lengths of an important subcomponent are independently and normally distributed with a mean of 120 cm and a standard deviation of 4.7 cm. Find the probability that if 3 are randomly selected, all 3 ha...

physics
A baseball thrown at an angle of 65.0^\circ above the horizontal strikes a building 16.0 {\rm m} away at a point 5.00 {\rm m} above the point from which it is thrown. Ignore air resistance. a) find the magnitude of the initial velocity of the baseball. b) find the magnitude of...

physics
A man stands on the roof of a 19.0 m tall building and throws a rock with a velocity of magnitude 30.0 m/s at an angle of 30.0 degrees above the horizontal. Ignore air resistance. Calculate the horizontal distance from the base of the building to the point where the rock strik...

AP Calculus
If f(x)=3x^2-x+2 then what is 2f(a)? What is f(2a)? What is f(a^2)? What is [f(a)]^2? What is f(a+h)?

English
Our state is bordered by Kansas to the west. Should west be capitalized...I was thinking it was a direction and didn't.
