Can a single force applied to body change both its translational and rotational motions? Explain.

Short Answer

Expert verified

Yes, a single force applied to body change both its translational and rotational motions

Step by step solution

01

Force

The definition of force is: The push or pull that causes a massed object to change its velocity. Force is an external agent that has the power to alter a body's resting or moving position. It has a direction and a magnitude.

02

Finding whether a single force applied to the body changes both its translational and rotational motions or not.

Let us take the example of a disk

When we apply tangential force to the rim of a disk, what would happen is:

(1) A net force would lead the disc to accelerate when we apply tangential force to the disk's rim.

(2) The disc would revolve about its centre of mass due to the torque created.

It would therefore simultaneously slide and spin.

Hence, we can say that a single force applied to the body change both its translational and rotational motions.

A car and a truck start from rest at the same instant, with the car initially at some distance behind the truck. The truck has a constant acceleration of20m/s2, and the car has an acceleration of3.40m/s2. The car overtakes the truck after the truck has moved60.0m. (a) How much time does it take the car to overtake the truck? (b) How far was the car behind the truck initially? (c) What is the speed of each when they are abreast? (d) On a single graph, sketch the position of each vehicle as a function of time. Takex=0at the initial location of the truck.

A jet fighter pilot wishes to accelerate from rest at a constant acceleration of to reach Mach 3 (three times the speed of sound) as quickly as possible. Experimental tests reveal that he will black out if this acceleration lasts for more than5.0s. Use331m/sfor the speed of sound. (a) Will the period of acceleration last long enough to cause him to black out? (b) What is the greatest speed he can reach with an acceleration ofbefore he blacks out?

Hot Jupiters. In 2004 astronomers reported the discovery of a large Jupiter-sized planet orbiting very close to the star HD鈥�179949 (hence the term 鈥渉ot Jupiter鈥�). The orbit was just19 the distance of Mercury from our sun, and it takes the planet only3.09days to make one orbit (assumed to be circular). (a) What is the mass of the star? Express your answer in kilograms and as a multiple of our sun鈥檚 mass. (b) How fast (in km>s) is this planet moving?
