Find the car's average velocity for the following time intervals: Time interval [1,3] feet/ second Time interval [2,3] feet/second

A Ferrari traveling well over the posted speed limit, passes a parked Tennessee State Trooper who decided to give chase. It takes the trooper 4.6 seconds to turn on the 'blue lights' and get the 'at rest' PW5000 powered Dodge interceptor moving. Then 8.3 seconds more to accelerate to its top speed and 63 seconds more to catch up with the speeder 3.5 km down the highway from the trooper's parking spot. Determine the average speed of the Ferrari over this distance in km/hr

An object A moves along the x-axis according to the equation: x(t) = 3.5t2+1.7t+14.0 where x is in meters while t is in seconds, the other object B moves along the x-axis with constant speed 10.0 m/s. At what time  the object A has the same instantaneous velocity  as the object B? State your answer in seconds to the nearest 0.01s.

For the following function models the position s(t)s(t) of an object moving along a stright line, where tt is in seconds and ss is in meters. s(t)=t2-6t Find the simplified expression for the average velocity from t=7t=7 to t=7+ht=7+h. s(t+h)-s(t)/h=?

If a particle increases in speed at a constant rate as it moves in the positive direction along an x axis, which of the following describes a plot of its velocity versus time? O plot has constant positive slope plot has constant negative slope O plot has zero slope

A car driving down a street passes a telephone pole and a passenger starts a stopwatch. The passenger stops the stopwatch when the car passes another telephone pole 52.1 m down the road and finds that it took exactly 3.39 s. What was the car's average velocity between the two telephone poles?

A car is traveling at 28.0 m/s when the driver suddenly applies the brakes, giving the car a constant deceleration. The car comes to a stop in a distance of 120.0 m. How fast was the car moving when it was 60.0 m past the point where the brakes were applied?

This is the vx-tgraph for an object moving along the x-axis. Which of the following descriptions of the motion is most accurate? Vx The object is speeding up at an increasing rate. The object's speed is changing at a steady rate. O The object is slowing down at an increasing rate. The object is slowing down at a decreasing rate. The object is speeding up at a decreasing rate.

A pick-up truck starts from rest and accelerates at a constant rate in a straight line. In the first two seconds, the van moves a distance of 5.0 meters.  How much additional distance will the van move three seconds (in the 2nd-5th second time interval) after the first two seconds of its motion?

A train starts from rest and accelerates uniformly, until it has traveled 5.6 km and acquired a velocity of 42 ms. The train then moves at a constant velocity of 42 m/s for 420 s. The train then slows down uniformly at 0.065 m/s2, until it is brought to a halt. The acceleration during the first 5.6 km of travel is closest to: O 0.20 m/s² O 0.14 m/s² O 0.19 m/s² 0.17 m/s² O 0.16 m/s²
