A2-kg object is falling downward with its speed increasing at a rate of 8m/s per second. We conjecture that there must be some other force acting on the object in addition to the downward pull of gravity. What can we say about this other force?

A. It has a magnitude of 2 N and points in the downward direction.

B. It has a magnitude of 16 N and points in the upward direction.

C. It has a magnitude of 36 N and points in the upward direction.

D. It has a magnitude of 4 N and points in the upward direction.

E. It has a magnitude of 20 N and points in the downward direction.

Expert Solution

downward force is mg = 2g = 2*10 = 20N

let upward force be F

net force = ma = 2*8 = 16N = 20 - F

F = 20 - 16 = 4N upwards

An object accelerates due west from rest, at a rate of 8m/s/s for 20s. After that time, it instantaneously turns 30 degrees north of west and moves with constant speed for 10s (at the speed it was going before turning). Finally it turns up, so that its path has an angle of elevation of 50 degrees above the horizontal and slows down to rest at a rate of 3m/s/s. What is the objects displacement when it arrives at rest? Thank...
