Wewaii [24]

Given :-

An elevator is moving vertically up with an acceleration a.

To Find :-

The force exerted on the floor by a passenger of mass m .

Solution :-

As the man is in a accelerated frame that is non inertial frame , we would have to think of a pseudo force .

The direction of this force is opposite to the direction of acceleration the frame and its magnitude is equal to the product of mass of the concerned body with the acceleration of the frame .

For the FBD refer to the attachment . From that ,

$\implies Weight_{apparent}= mg + ma$

Hence option d is correct choice .

I hope this helps .

A ball is tossed into the air from height of 8 feet with an initial velocity of 8 feet per second. find the time r(in seconds) i

-Dominant- [34]

For this case we have the following equation:
-16t + 8t + 8 = 0
The first thing we must do is rewrite the equation correctly.
We have then:
-16t ^ 2 + 8t + 8 = 0
Solving the polynomial we have:
t1 = -1/2
t2 = 1
We discard the negative root because we want to find the time.
Answer:
it takes for the object to reach the ground about:
t = 1 second
