A boat accelerates from 0 m/s (rest) at the starting point to reach a speed of 45.0 km/h over a distance of 90.0 m, and then continues with the same constant acceleration for another 15.0 s before slowing down to 30.0 km/h over a distance of 150. m. Another boat begins to accelerate from 0 m/s (rest) at the same starting point as the first boat and catches up to the first boat within 45.0 s. (a) What is the acceleration of the second boat. (b) What is the time it takes the first boat to cover the first 90 m. (c) What is the speed of the second boat when it catches up to the first boat

Light-rail passenger trains that provide transportation within and between cities speed up and slow down with a nearly constant (and quite modest) acceleration. A train travels through a congested part of town at 5.0 m/s. Once free of this area, it speeds up to 12 m/s in 8.0 s. At the edge of town, the driver again accelerates, with the same acceleration, for another 16s to reach a higher cruising speed. What is the final speed?
On a one lane road, a person driving a car at v₁ = 79 mi/h suddenly notices a truck a distance d = 14 m in front of him. That truck is moving in the same direction at a constant velocity of v₂ = 32 mi/h. In order to avoid a collision, the person in the car has to reduce their speed to v2 in a time interval At. By slamming on their brakes, the driver can give the car a maximum negative acceleration of ar. Assume the acceleration is constant and that the direction of motion of the car is the positive direction, so the acceleration ar <0. Refer to the figure. d Part (a) Assuming the driver just barely avoids a collision, what is the final distance, in meters, between the car and the truck? Part (b) Enter an expression for the distance Ax₂ traveled by the truck in the time At, in terms of the quantities defined in the problem statement. Part (c) Find an expression for the distance Ax₁ traveled by the car in the time At, assuming the driver brakes as hard as they can. Part (d) Relate the…
A car starts from rest at a stop sign. It accelerates at 4.0 m/s2 for 6.0 s, coasts for 2.0 s, and then slows down at a rate of 3.0 m/s2 for the next stop sign. How far apart are the stop signs?

A car travels a total distance of 300m.During the first half of this distance, the car starts from rest and accelerates at a constant rate of 1.75 m/s2.Over the second half of the distance the car slows at a constant rate to a final velocity of 12.5 m/s. Determine the acceleration of the car during the second half of the trip.(hint: break problem into two parts and determine final velocity during first part) Determine how long it takes the car to complete the entire trip.

In the Daytona 500 auto race, a Ford Thunderbird and a Mercedes Benz are moving side by side down a straightaway at 66.0 m/s. The driver of the Thunderbird realizes that she must make a pit stop, and she smoothly slows to a stop over a distance of 250 m. She spends 5.00 s in the pit and then accelerates out, reaching her previous speed of 66.0 m/s after a distance of 360 m. At this point how far has the Thunderbird fallen behind the Mercedes Benz, which has continued at a constant speed?
You are driving your car along a country road at a speed of 23.6 m/s. As you come over the crest of a hill, you notice a farm tractor 25.0 m ahead of you on the road, moving in the same direction as you at a speed of 10.0 m/s. You immediately slam on your brakes and slow down with a constant acceleration of magnitude 7.20 m/s2. How far is the tractor in front of you when you finally stop?
