Solar Energy is the answer to the question tell me if i`m wrong
Answer:
<h2> 0.041kg</h2>
Explanation:
Step one:
given data
initial velocity u= 0m/s
Force F= 443N
time t= 4.3 ms= 0.0043seconds
final velocity v= 45.7m/s
Step two:
Required
mass m
we know that the expression for impulse is given as
Ft=mv
make m subject of the formula
m=Ft/v
substitute we have
m=443*0.0043/45.7
m=1.90/45.7
m=0.04kg
The mass of the ball is 0.041kg
To compare and rank each one's acceleration, get the acceleration of each person by using the formula, Acceleration = Velocity/Time
Xander = 4.5mps / 3.5s = 1.29m/s^2
Finley = 3.6mps/4.2s = 0.86m/s^2
Max = 7.3mps/1.2s = 6.08m/s^2
Based on the answers above, the least acceleration was done by Finley, then Xander had higher acceleration than Finley, while most acceleration was done by Max.
