Problem 1:   Two trucks both cover a straight distance, d = 297 m, in time t = 11.5 s. Truck A moves at a constant velocity (vA). Truck B moves at a constant acceleration (aB), starting from an initial velocity of v0B = 5.9 m/s. Assume both trucks are moving in the positive x-direction.   Part (b)  What is the final velocity of Truck B?   Part (c)  What is the acceleration of Truck B?

By shooting water from its rear, a squid can provide itself with jet propulsion. Suppose a squid launches itself vertically upward from rest with constant upward acceleration for 0.890 s and travels a vertically upward distance of 2.72 m.  The squid then turns off its jets and continues its flight in free fall.  (a) What is the magnitude of the squid’s acceleration during the time it is jetting? (b) How long does it take the squid to reach its maximum height while in free-fall after jetting? (c) What maximum height did the squid attain?

Referring to the figure, a truck drives a distance d=30.1m in the positive x direction in a time t1=17.2s, at which point the truck brakes, coming to rest in t2=8.13s.  Part A: What is the truck's average velocity in the horizontal direction, in meters per second, during the t1 time period? Part B: Assuming the truck started from rest and moved with a constant acceleration, what was the acceleration, in meters per suqared second, during the time interval t1? Part C: What was the truck's instananeous velocity in the horizontal direction, in meters per second, when it began braking? And using the result from the previous answer, what was the truck's horizontal component of acceleration, in meters per squared second, during the braking period?  Please explain how you got your answer in detail.

On a one lane road, a person driving a car at v1 = 58 mi/h suddenly notices a truck 1.1 mi in front of him. That truck is moving in the same direction at v2 = 35 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 magnitude of 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.  1. Use the expressions you entered in parts (c) and (f) and enter an expression for a in terms of d, v1, and v2.  a = ( v2 - v1 )/Δt   Δt = ( 2 ) ( d )/( v1 - v2 ) 2. Calculate the value of a in meters per second squared.

A helicopter carrying Dr. Evil takes off with a constant upward acceleration of 7.0 m/s2m/s2. Secret agent Austin Powers jumps on just as the helicopter lifts off the ground. After the two men struggle for 11.0 ss, Powers shuts off the engine and steps out of the helicopter. Assume that the helicopter is in free fall after its engine is shut off, and ignore the effects of air resistance.   What is the maximum height above ground reached by the helicopter?   Powers deploys a jet pack strapped on his back 7.0 ss after leaving the helicopter, and then he has a constant downward acceleration with magnitude 3.0 m/s2m/s2. How far is Powers above the ground when the helicopter crashes into the ground?

(A A person walks first at a constant speed of 4.80 m/s along a straight line from point to point and then back along the line from B to A at a constant speed of 3.05 m/s What is her average velocity over the entire trip? B m/s

You are initially at rest in your car. At time t = 0, a truck passes you moving at 25.0 m/s. You thenimmediately begin to accelerate at 3.00 m/s^2 in the same direction the truck is moving. If youmaintain this acceleration, and the truck maintains its speed, when will you overtake the truck? Group of answer choices t = 5.00 s t = 16.7 s t = 2.50 s t = 25.0 s t = 8.33 s

Problem 1. You are driving at 31.0 m/s when the truck ahead of you comes to a halt 200.0 m away from your bumper. Your brakes are in poor condition and you decelerate at a constant rate of 2.5 m/s. (a) How close do you come to the bumper of the truck? (b) How long does it take you to come to a stop? (c) Graph v versus t for the motion.

Car A is traveling on a highway at a constant speed.  Initial velocity A = 80 mi/h and is 380 ft from the entrance of an on-ramp when car B enters the acceleration lane at that point at a speedInitial speed B = 20.0 mi/h. Car B accelerates uniformly and enters the main traffic lane after traveling 290 ft in 3.3 s. It then continues to accelerate at the same rate until it reaches a speed of 80 mi/h, which it maintains. Determine the final distance between the two cars (in ft).
