    Physic problem
    If a projectile enters the liquid in a tank horizontally with a velocity of 800 meters /sec, and that liquid exerts a deceleration of 95 m/s/s, how many seconds will the projectile travel in the fluid before its forward velocity drops to zero?

    Physics problem
    A car is traveling at a speed of 45 m/s and the driver sees a traffic light turn red. After 0.530 s the driver applies his brakes and the car decelerates at a rate of 6.50 m/s/s. What is the stopping distance of the car, measured from where the driver first recognizes the red light?

    Please refer to this announcement

    Do not simply retype or paste a question from your book or study material

    We won't do your homework questions for you.
    You were given the assignment for you to learn.

    If you come up with your own answer and post it for us to critique that is within reason.

    If you have some SPECIFIC questions that you couldn't find or didn't understand, we may help with that.
    But this is your assignment, so show us you have at least attempted to complete it on your own.

    Thank you.

    Those all have to deal with kinematics. Do you know your formulae?
