The answer would be c not that sure tho
Answer:
28.73 m from the base of the cliff collide happen
Explanation:
Equation for ball dropped from 50 cliff is reaches distance x in t seconds isi given by
stone is thrown up from the bottom with speed u=24 m/s . it reaches distance y when stone collide with ball.(g is negative here)
we know that total distance traveled by ball and stone is 50 m
adding equation 1 and 2, we get time t
substitute this time in equation 2, we can get the required distance where they collide
28.73 m from the base of the cliff collide happen
Answer:
Th average force impact is
Explanation:
From the question we are told that
The mass of the golf ball is
The angle made is
The range of the golf ball is
The duration of contact is
Generally the range of the golf ball is mathematically represented as
Here v is the velocity with which the golf club propelled it with, making v the subject
=>
=>
Generally the change in momentum of the golf ball is mathematically represented as
here u is the initial velocity of the ball before being stroked and the value is 0 m/s
=>
Generally the average force of impact is mathematically represented as
=>
=>
(ANSWER: 300 ft-lbs) It’s pretty easy once you understand the process. Basically all you need to do is multiply 100 and 3. As you know, 100*3=300. Therefore, the answer should be 300 ft-lbs.
