*Problem 4: т A car is moving with an initial velocity vo = 26 £– at an initial position of 7, =-10 £ m. The driver sees a stop m sign 50 m ahead. The car has a maximum braking acceleration of ả = -5£ . a) Find the time required for the car to stop. (A: 5.2(s)) b) Find the final position of the car. Did the car stop before the stop sign? (A: 57.4(m))

Suppose a car is traveling at +20.3 m/s, and the driver sees a traffic light turn red. After 0.232 s has elapsed (the reaction time), the driver applies the brakes, and the car decelerates at 8.00 m/s?. What is the stopping distance of the car, as measured from the point where the driver first notices the red light? Number Units

A baseball is hit so that it travels straight upward after being struck by the bat. A fan observes that it takes 3.10 s for the ball to reach its maximum height. (a) Find the ball's initial velocity. m/s upward (b) Find the height it reaches. m

Please help with 1a

A car is moving with an initial velocity ?⃗0 = 26 ?̂ ? ? at an initial position of ?⃗0 = −10 ?̂ ?. The driver sees a stop sign 50 ? ahead. The car has a maximum braking acceleration of ?⃗ = −5?̂ ? ? 2 . a) Find the time required for the car to stop. (?: 5.2(?)) b) Find the final position of the car. Did the car stop before the stop sign? (?: 57.4(?)) c) Plot the acceleration vs time d) Plot the velocity vs time e) Plot the position vs time f) Be sure to indicate how the slopes of the graphs correspond to other values

Short computation The position of an object as a function of time is given by x(t) = bt3 - ct2 + et - f, where b = 2.1 m/s³, c = 3.2 m/s², e = 7 m/s and f = 6.8 m. Find the average acceleration over the first 1.21 seconds. davg = Remember to include a "-" if the average acceleration is negative. Do not include a "+" for a positive value. m/s² Report your numerical answer below, assuming three significant figures. D

NASA has fired a rocket straight up into the air from ground level with an unknown initial velocity. It reaches a maximum height of 164,000 feet. This happened in Cape Canaveral therefore the rocket is under the acceleration of Earth's gavity in which we all know is -32 ft/sec/sec.                                           Please round your answers to two decimal places. a). Find the time it takes for the rocket to reach maximum height. b). find the initial velocity necessary to reach that height.

can  you please help me really quick!! thank you i need it in less than 10 minutes
