Amechanic uses a hydraulic car jack to lift the front end of a car to change the oil. the jack used exerts 8,915 n of force from the larger piston. to pump the jack, 444 n of force is exerted on the small piston, which has an area of 3.14 cm2. what is the area of the large piston?

63.05 cm²

Explanation:

We use Pascals law to find the answer.

The law says that in an incomprehensible , non-viscous fluid the pressure applied will transmit through out the fluid without a change.

So, Pressure on larger piston = pressure on smaller piston.

                                     A ≅ 63.05 cm²

root word, prefixes, and suffixes

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
