*not sure about the answer but here we go*
Mass = 425 kg
distance = 614.4 m
acceleration = 1.8 m/s²
Answer :
Count Force first.
F = 425 × 1,8
F = 765 N ✅
Now let's count Work.
W = 765 × 614.4
W = 470016 J ✅
Answer: 3.55 s and 0.83 s
Explanation:
The height (in feet) of the softball is given by:
s(t)=-16t²+70t+3
we need to find the time when the ball is 50 feet above the ground:
⇒50 = -16t²+70t+3
we need to solve the quadratic equation
⇒16t²-70t+47 = 0
This gives two values of time: 3.55 s and 0.83 s
