3.0 A i got it off Quizlet and there usually always right lol can't submit tho my answers to short.... Dot dot dot
Answer:
Vf = final velocity = 1.96 [m/s]
Explanation:
To solve this problem we must use the following equation of kinematics.
where:
Vf = final velocity [m/s]
Vo = initial velocity = 9.98 [m/s]
g = gravity acceleration = 9.81 [m/s²]
x = vertical distance [m]
![v_{f}^{2}=(9.98)^{2}-2*9.81*4.88\\v_{f}^{2} = 99.6-95.74\\v_{f}=\sqrt{3.8544}\\v_{f}=1.96[m/s]](https://tex.z-dn.net/?f=v_%7Bf%7D%5E%7B2%7D%3D%289.98%29%5E%7B2%7D-2%2A9.81%2A4.88%5C%5Cv_%7Bf%7D%5E%7B2%7D%20%3D%2099.6-95.74%5C%5Cv_%7Bf%7D%3D%5Csqrt%7B3.8544%7D%5C%5Cv_%7Bf%7D%3D1.96%5Bm%2Fs%5D)
Note: The negative sign of the gravity acceleration means that the gravity acceleration is pointing in the opposite direction of the movement.
Answer:
150 newtons
Explanation:
F = ma
force = mass * acceleration
the mass is 10 kg, and the accelration is 15 m/s^2
10*15 = 150
the force unit that matches with meters/second and kg is newtons
F =ma
150 newtons = 10 kg * 15 m/s^2
Wow! Very simple. Use the equation for momentum which is p=mv. You know your momentum and velocity, so do 120=m(4), now solve for m, which is 30. The mass of the child is 30 kg
