On a one lane road, a person driving a car at v1 = 76 mi/h suddenly notices a truck d = 1.9 mi in front of him. That truck is moving in the same direction at v2 = 45 mi/h. In order to avoid a collision, the person has to reduce the speed of his car to v2 during time interval Δt. The smallest acceleration required for the car to avoid a collision is a. During this problem, assume the direction of motion of the car is the positive direction. Refer to the figure below. a)Enter an expression, in terms of defined quantities, for the distance, Δx2, traveled by the truck during the time interval Δt. b)Enter an expression for the distance, Δx1, traveled by the car in terms of v1, v2 and a. c)Enter an expression for the acceleration of the car, a, in terms of v1, v2, and Δt. d)Enter an expression for Δx1 in terms of Δx2 and d when the driver just barely avoids collision. e)Enter an expression for Δx1 in terms of v1, v2, and Δt. f)Enter an expression for Δt in terms of d, v1, and v2. g)…
A jet plane comes in for a landing with a speed of 100m/s, and its acceleration can have a maximum magnitude of 5.00m/s2 as it comes to rest from the instant the plane touches the runway, what is the minimum time interval needed before it can come to rest?
A small bag of sand is released from an ascending hot‑air balloon whose constant, upward velocity is ?0=2.95 m/s. Knowing that at the time of the release the balloon was 57.8 m above the ground, determine the time ? it takes for the bag to reach the ground from the moment of its release. Use ?=9.81 m/s^2. ? = _____________ s
A football player carrying the ball runs straight ahead at the line of scrimmage and directly into a wall of defensive linemen. The ball carrier has an initial speed of 8.56 m/s and is stopped in a time interval of 0.182 s. Find the magnitude and direction of his average acceleration.
A golfer wants to put the ball into the final hole which lies 7.0 m away from the ball and up a slight hill. Because of the incline while the ball moves up this hill will experience a constant deceleration of 1.8 m/s^2. Which initial velocity should the golfer give the ball if they want to make it go precisely into the hole? Please answer in m/s
A person hits a trampoline while moving downward with a speed of 9 m/s and rebounds a short time later with roughly the same speed upward. If the person is in contact with the trampoline for about 1.8 s, what are the magnitude and direction of the person’s average acceleration during this time interval? (Hint: You can ignore the effects due to gravity
A jetliner, travelling northward, is landing with a speed of 69 m/ s. Once the jet touches down, it has 750 m of runway in which to reduce its speed to 6.1 m/ s. Compute the average acceleration (magnitude and direction) of the plane during landing.

An object is thrown straight up with an initial velocity of 13.4 m/s. What time interval elapses between the object's being thrown and its return to the original launch point? (Acceleration due to gravity is 9.80 m/s2.)
A car is 126 m from a stop sign and traveling toward the sign at 29 m/s. At this time, the driver suddenly realizes that she must stop the car. If it takes 0.200 s for the driver to apply the brakes, what must be the magnitude of the constant acceleration of the car after the brakes are applied so that the car will come to rest at the stop sign?
