A horizontal force of 7000N is applied to vehicle of mass 400kg which is inifidly addres at a horizontal surface. if the total force opposing the motion is constant at 800N (a) calculate, aceleration of the vehicle (b) kinetic energy of the vehicle after 5 seconds after the force is applied (c) total power developed after force applied (5 seconds)

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

explanation:

to push or pull an object in a certain direction is known as force. a force in moving an object from one place to another.

force depends on the mass of an object. so, more is the mass of an object more will be the force required to move the object.

thus, we can conclude that the use of force to move an object is push or pull.
