A runner of mass 53.9 kg starts from rest and accelerates with a constant acceleration of 1.36 m/s^2 until she reaches a velocity of 5.83 m/s. She then continues running at this constant velocity. How long does the runner take to travel 153 m? ttotal = [ ]S
A low-flying crop-duster 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
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

17. Two runners start running in the same direction at the same instant, t- 0.00. Runner A starts from a point that is 20.0 meters in front of runner B. Runner A starts with and maintains a constant acceleration of 2.00 m/s for 3.00 seconds, and then runs at a constant velocity. Runner B starts with and maintains a constant acceleration of 2.20 m/s for 4.0 seconds, and then runs at a constant velocity. a. Calculate the time when runner...

An electric vehicle starts from rest and accelerates at a rate of 2.2 m/s2 in a straight line until it reaches a speed of 22 m/s. The vehicle then slows at a constant rate of 1.0 m/s2 until it stops.(a) How much time elapses from start to stop (in seconds)?(b) How far does the vehicle travel from start to stop (in meters)?

Air Force One accelerates from rest at a constant rate of 5.80 m/sec^2 along a runway that is 3.47 km long. Assume that the plane reaches takeoff speed exactly at the end of the runway. a) what is the time needed to take off? b) What is the speed of the plane as it takes off?

A car starts from rest and accelerates at a constant rate until it reaches 75 mi/hr in a distance of 220 ft, at which time the clutch is disengaged. The car then slows down to a velocity of 25 mi/hr in an additional distance of 570 ft with a deceleration which is proportional to its velocity. Find the time t for the car to travel the 790 ft.
