Two foreces act on a block of mass 4.5 kg resting on
africtionless, horizontal surface, as shown. the horizontal force
is3.7 n; the other force of 5.9 n acts at an angle of 43 degrees
fromthe horizontal. what is the magnitude of the acceleration of
theblock?

Explanation:

Given

mass of block(m)=4.5 kg

Horizontal force()=3.7 N

another force F at angle of

if F is pulling Block then

Net Normal reaction=mg-Fsin43=40.12 N

Net Force in Horizontal direction =3.7+Fcos43

=3.7+4.31=8.014 N

thus Net acceleration is a

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
