B is the answer to this question. To solve this, you need to do the following processes: The first thing is you need to find VOY. Then, you need to look for T. Look for YMAX, and you will get the...Read More

4 seconds-it will still take 4 seconds to fall 78.4 meters use the equation y = 0.5 g t2 and substitute -9.8 m/s/s for g. the vertical displacement must then be subtracted from the initial height...Read More

A and B hit the ground at the same time.

If two objects are dropped from the same height with only the force of gravity acting upon them, the acceleration of their descent is an equal -9.8...Read More

Constant velocity

In projectile motion the x and y components are considered independently. Therefore even though acceleration due to the force of gravity is present vertically,...Read More

Using trig function - you need to the vertcal compoent which is the opposite side i.e. 100sin60

30.4 m.s-1

Acceleration (a) of a projectile is the same as the force of gravity, 9.8m.s-2. A rule to remember is that when an object is slowing down, the acceleration is in the opposite...Read More

The 30° angle because the ball goes further
The ball’s velocity increases, and the distance the ball falls in one second increases

-9.8m/s^2 I think is the correct answer. no matter the object is in the upward or downward direction it will always have constant acceleration due to gravity -9.8m/s^2.
