Chapter 1: Q3DQ (page 57)

Can an object with constant acceleration reverse its direction of travel? Can it reverse its direction twice? In both cases, explain your reasoning.

Short Answer

Expert verified

There is no possibility to change the direction twice with constant acceleration.

Step by step solution

01

Step 1:

Acceleration is the rate by which the velocity wills changes with time with respect to both speed and direction.

02

Explanation

Any object will change the direction at once with acceleration but not the second time. Because as the speed increases acceleration is positive and acceleration is negative when speed decreases.

Example: If an object is moving with constant magnitude and reaches its maximum height, then it will stop a moment and changes the direction of motion.

You hold a hose at waist height and spray water horizontally with it. The hose nozzle has a diameter of 1.80 cm, and the water splashes on the ground a distance of 0.950 cm horizontally from the nozzle. If you constrict the nozzle to a diameter of 0.750 cm, how far from the nozzle, horizontally, will the water travel before it hits the ground? (Ignore air resistance.)

A particle of mass 3m is located 1.00鈥�mfrom a particle of mass m.

(a) Where should you put a third mass M so that the net gravitational force on M due to the two masses is precisely zero?

(b) Is the equilibrium of M at this point stable or unstable (i) for points along the line connecting m and 3m, and (ii) for points along the line passing through M and perpendicular to the line connecting m and 3m?

A cargo ship travels from the Atlantic Ocean (salt water) to Lake Ontario (freshwater) via the St. Lawrence River. The ship rides several centimeters lower in the water in Lake Ontario than it did in the ocean. Explain

The driver of a car wishes to pass a truck that is traveling at a constant speed of20.0m/s(about41mil/h). Initially, the car is also traveling at20.0m/s, and its front bumper is24.0mbehind the truck鈥檚 rear bumper. The car accelerates at a constant 0.600m/s2, then pulls back into the truck鈥檚 lane when the rear of the car is26.0mahead of the front of the truck. The car islong, and the truck is 21.0m long. (a) How much time is required for the car to pass the truck? (b) What distance does the car travel during this time? (c) What is the final speed of the car?
