heloo guys i have these homework assignment i need help on it.. 1- A car moving initially at 48 mi/h begins decelerating at a constant rate 110 ft short of a stoplight.If the car comes to a full stop just at the light, what is the magnitude of its acceleration? Express your answer to two significant figures and include the appropriate units. 2- A gallon of paint covers 420 ft2 .What is its coverage in m2/L? 3- A car moving...
A car moving initially at a speed of 52.0 mi/h and weighing 3,000 lb is brought to a stop in a distance of 205 ft. Find (a) the breaking force (b) the time required to stop. Assuming the same braking force find (a) the distance and (d) the time required to stop if the car were going 26.0mi/h initially. (Hint: Convert to SI units)
Suppose that instead of moving at a constant speed, the car in
VP 2.9.1 begins to accelerate at 1 m/s2 at the
moment it passes the school crossing. How much time elapses before
the officer catches up to the car?
What is the position of the car when the officer catches up to
it?
PART D AND PART E. THANK YOU
VP 2.9.1 Part A A motorist is traveling at a constant velocity of v = 13.0 m/s and passes...
Draw a correctly labeled motion diagram for each of the following scenarios. Make sure you include both velocity and acceleration vectors. a. A car travels along a straight, flat road at a steady speed. b. A truck slows down and comes to a stop as it approaches a red traffic light. c. A train accelerates as it leaves the train station and then keeps moving at a constant speed. d. A bungee jumper jumps from a high bridge. Initially the...
