Q. A sketech of a position-time graph that would corresponding to the following descriptions. Just general shapes, no all details will be given.
1) A runner starts at the starting blocks and accelerates for 6.0seconds.
2) A car is moving at a constant velocity for 3.0s until it is 3.0 m from a yellow light. It slows to a stop in 2.0s. It remains stopped for 50.0s and then speeds up for 2.0s.
The heat of vaporization of ethyl alcohol is about 200 cal/g. If 2.8kg of it were allowed to vaporize in the refrigerator, how many grams of ice would be formed from 0 °C water.
Status Newton's First Law of motion.
A more realistic car would cause the wheels to spin in a manner that would result in the ground pushing it forward with a constant force (in contrast to the constant power in Part A). If such a sports car went from zero to 30.0 in time 1.10 , how ..
Two points are located on a rigid wheel that is rotating with an increasing velocity about fixed axis. The axis is perpendicular to the wheel at its center. Point 1 is located on the rim and point 2 is halfway between rim and axis .at any given insta..

A box with a mass of 8 kg is lifted (without acceleration) through a height of 9 m, in order to place it upon the shelf of the closet.
A man exerts a 328 N force to move a box across a 3.55-m patch of ice. How much work does he do on the box.
The bullet penetrates into the block and stops due to its friction with the block. The compound system of the block plus the bullet rises to a height of 11 cm along a circular arc with a 20 cm radius A bullet with a m1 = 30.0 g mass is fired horizont..
Find the modulation index corresponding to the given trapezoidal pattern for the AM signal.
Two people with a combined mass of 120kg hop into an old car with worn-out shock absorbers. This causes the springs to compress by 8.30 cm. When the car hits a bump in the road, it oscillates up and down with a period of 1.70s.
A person's prescription for her new bifocal glasses calls for a refractive power of -0.461 diopters in the distance-vision part, & a power of +1.83 diopters in the close-vision part. Compute the near & far points of this person's uncorrected visio..
