I’m guessing is because she uses force to throw the ball, allowing the energy to move the person.
sorry if it’s not 100% correct
Answer:
Explanation:
a = F/m = 7500/2000 = 3.75 m/s²
v² = u² + 2as
s = (v² - u²) / 2a
s = (0² - 45²) / (2(-3.75))
s = 270 m
Answer:
No. Because it would correspond to zero Instantaneous acceleration.

Answer:
- F= 25N
- ∆l=280cm
- K=?
- you apply the formula = K:F/∆l
- = 0,089N/cm
Answer:10842.33m/s
Explanation:
F=qvBsine
V=f/(qBsine)
V=(3.5×10^-2)÷(8.4×10^-4×6.7×10^-3×sin35)
V=10842.33m/s
