A ride-sharing car moving along a straight section of road starts from rest, accelerating at 2.00 m/s2 until it reaches a speed of 32.0 m/s. Then the vehicle moves for 41.0 s at constant speed until the brakes are applied, stopping the vehicle in a uniform manner in an additional 5.00 s. (a) How long is the ride-sharing car in motion (in s)? 62 (b) What is the average velocity of the ride-sharing car for the motion described? (Enter the...
Car A is parked along the northbound lane of a highway, and car B is traveling in the southbound lane at a constant speed of 60 mi/h. At t = 0, A starts and accelerates at a constant rate aA, while at t = 5 s, B begins to slow down with a constant deceleration of magnitude aA/6. Knowing that when the cars pass each other x = 294 ft and vA = vB, determine (a) the acceleration aA, (b)...

A low-flying cropduster A is moving with a constant speed of 40 m/s in the horizontal circle of radius 300 m. As it passes the twelve-o'clock position shown at time t = 0 car B starts from rest from the position shown and accelerates along the straight road at the constant rate of 3m / (s ^ 2) until it reaches a speed of 30m / s after which it maintains that constant speed. Determine the velocity and acceleration of...

An airplane reaches its takeoff speed of 60 m/s with constant acceleration in 30 s, starting from rest. The time it takes to go from 40 m/s to 60 m / s is: A car starts moving from rest with an acceleration of 0.40 m/ s2. A minute later the acceleration stops, and the car moves with constant speed for 5.0 minutes. The car's brakes are finally applied and stops in 2.0 minutes slowing evenly. The total distance traveled by...
