A 0.12 kg arrow is shot vertically at a target that is suspended 80 meters above the ground. If the arrow hits the target with a speed of 22 m/s, the initial speed of the arrow was m/s. (Round to the nearest whole number) 1 point

If forces acting on an object are unbalanced, which factors may result fron an unbalanced force? check all that apply

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.
