Chapter 1, Problem 17P

A car moves along a circular path with a radius of curvature equal to 40 m. way your speed is increased by at= (3t) m/s², where t is given in seconds. That said, after the car has moved s = 20 m from rest at O ​​(origin), determine: (a) the intensity of your speed (b) the intensity of its acceleration

Two water streams of the same size and speed crash like in the picture. Determine the speed V of the resultant combined stream. Gravity can be ignored. Express the result in [ft/s]

A freight train travels at v = 60(1-e-t) ft/s, where t is the elapsed time in seconds.Determine the distance traveled in three seconds, and the acceleration at this time. Draw the necessary diagrams.

A particle moves along a path according to the equations      x = 9 - t4/9  and  y = t2/3 where x and y are in meters and t is in seconds. Determine the magnitude of the velocity (in m/s) of the particle in 1.97 seconds.

If the end of the cable at A is pulled down with a speed of 23 m/s, determine the speed at which block B rises.

As a train accelerates uniformly it passes successive kilometer marks while traveling at velocitiesof 3 m/s and then 12 m/s. Determine the train’s velocity when it passes the next kilometer markand the time it takes to travel the 2-km distance.

Determine the time required for a car to travel 1 km along a road if the car starts from rest, reaches a maximum speed at some intermediate point, and then stops at the end of the road. The car can accelerate at 1.5 m/s2 and decelerate at 2 m/s2.

A stone was dropped freely from a balloon at a height of 190 m. above the ground. The balloon is moving upward at a speed of 30 m/s. Determine the velocity of the stone as it hits the ground.

Initially, the car travels along a straight road with a speed of 35 m/s. If the brakes are applied and the speed of the car is reduced to 10m/s in 15 s, determine the constant deceleration of the car.
