I feel so dump. I've never taken physics in high school, and now I'm struggling on my second problem. And it's only the beginning of the term
. Can someone pls help.
If a person on a bike is at rest and pushes himself forward with a constant acceleration of 4.0m/s^2. what is his speed after 6.0?
that would be:V=12.0m/s
but this is the one that really getting to me.
For an additional 6.0s, at the same constant speed, the biker forgot his shoes and presses the brakes that bring him to a stop at 5.0s. What is his acceleration? Is it positive
*I've been working on this problem for more than 10hours, and I'm just frustrated at not knowing.I've tried all the formulas. I understand the constant acceleration but when it gets to the part where he presses the brake its really tricky cause there is only time. :surprise:
No mention of distance, velocity, and etc.
Can anyone help..pls
?
