Answer:

C. 250g mass on the left

Explanation:

As the given figure there are two forces on the box placed on the table

1) due to 250 gram there will be a force which will pull it towards right

2) due to 100 g mass which will pull it downwards

now if we wish to move the block only in downward direction then we have to add a force on the block that will counterbalance the force towards right direction

so here it must have a force towards left which will balance the force of 250 g mass towards right

so it would be

C. 250g mass on the left

On level ground a shell is fired with an initial velocity of 49.0 m/s at 70.0 โ above the horizontal and feels no appreciable ai
xenn [34]

Answer:

Horizontal component = 16.8 m/s

Vertical component = 46.0 m/s

Explanation:

If we denote the initial velocity by <em>v</em> and the angle above the horizontal by <em>θ</em>,

the horizontal component of this initial velocity is given by

v_x = v\cos \theta

v_x = (49.0\text{ m/s})\cos\,(70.0^\circ) = 16.8\text{ m/s}

The vertical component is given by

v_y = v\sin\theta

v_x = (49.0\text{ m/s})\sin\,(70.0^\circ) = 46.0\text{ m/s}
