The gravitational force acting on a lead ball is much larger than that acting on a wooden ball of the same size. when both are dropped, does the lead ball accelerate at the same rate as the wooden ball? explain. a. yes, they both accelerate at the same rate but the forces are different because their masses are different. b. yes, they will accelerate at the same rate but only if the effect of air resistance is negligible on the lead ball. c. no, they accelerate at the different rates because of their difference in size.

a. They both accelerate at the same rate but the forces are different because their masses are different

Explanation:

Firstly, as both the balls are falling under the action of gravity, the acceleration of both ball would be constant and equal to acceleration due to gravity (9.8 m/s2). However, the velocity of the objects falling under the action of gravity keep changing.

Secondly, the forces on object can be found by using formula:

Since, both balls are of different material their masses are different. Hence, the forces acting on both balls will be different.

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
