Answer:
Explanation:
Time of flight = 2 x u sinα / g where u sinα is vertical component of projectile's velocity u .
So Time of flight = 2 x vertical component / g
vertical component = constant
g is also constant so
Time of flight will also be constant .
It will remain unchanged .
Answer:
T = 451.26 N
Explanation:
It is given that,
The mass of block, m = 46 kg
Mass of the chain, m' = 19 kg
Length of the chain, l = 1.9 m
Let T is the the tension in the chain at the point where the chain is supporting the block. It is clearly equal to the product of mass and acceleration.


T = 451.26 N
So, the tension in the chain at the point where the chain is supporting the block is 451.26 N. Hence, this is the required solution.

I really need help with my homework. Sorry
Answer:
140 beats per minute
Explanation:
There are 60 seconds in a minute and we know that Sherry felt 14 beats in 6 seconds if you multiply 6 by 10 you get 60 seconds which can be 1 minute. Then you multiply 14 by 10 since you 14 by 10 since you multiplied 6 by 10 and you get 140 beats per minute.
To solve this problem it is necessary to use the concepts of Force of a spring through Hooke's law, therefore,

Where,
k = Spring constant
x = Displacement
Initially our values are given,


PART A ) With this values we can calculate the spring constant rearranging the previous equation,



PART B) Since the constant is unique to the spring, we can now calculate the force through the new elongation (0.38cm), that is



Therefore the weight of another person is 265.79N.
