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?

A car and a train move together along straight, parallel paths with the same constant cruising speed v0. At t=0 the car driver notices a red light ahead and slows down with constant acceleration −a0. Just as the car comes to a full stop, the light immediately turns green, and the car then accelerates back to its original speed v0 with constant acceleration a0. During the same time interval, the train continues to travel at the constant speed v0. How...

A sports car moving at constant velocity travels 110 m in 5.0 s . 1.)If it then brakes and comes to a stop in 4.3 s , what is the magnitude of its acceleration (assumed constant) in m/s2? 2.)Express the answer in terms of "g's," where g=9.80m/s2. Express your answer using two significant figures.

An unmarked police car traveling a constant 95 km/h is passed by a speeder traveling 140 km/h. Precisely 1.00 s after the speeder passes, the police officer steps on the accelerator; if the police car's acceleration is 2.60 m/s2 , how much time passes after the police car is passed by a speeder and before the police car overtakes the speeder (assumed moving at constant speed)? Express your answer with the appropriate units.

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...
