A projectile's horizontal range on level ground is r=v20sin2θ/g. at what launch angle or angles will the projectile land at half
Ksju [112]

As given the formula of range is

R = \frac{v^2sin2\theta}{g}

now for the maximum range

\theta = 45

R_{max} = \frac{v^2}{g}

now for half of this maximum range we will have

\frac{R_{max}}{2} = \frac{v^2sin2\theta}{g}

\frac{v^2}{2g} = \frac{v^2sin2\theta}{g}

now from above we have

sin2\theta = \frac{1}{2}

so two possible values for above is given as

\theta = 15 degree, 75 degree

so above two angle we will have half of maximum range

3. A force of 90N pushes downward at an angle of 32° to the horizontal on an object resting on the floor. The
Nonamiya [84]

F = m × g

Now when, a force acts on the object at an angle and in downwards, thus formula becomes:

= N = mg + F sin(x)

Here,

  • N = normal force, m = mass , g = acceleration due to gravity, F = outside force, x = the angle formed

See, as we habe to calculate the weight, which is m × g, thus we will recreate thus formula like thus:

= N = w + F sin(x) --------- [Weight = w]

Now, the solutions becomes easy from here, just put the values:

= N = w + F sin(x)

= 200 = w + 90 × sin(32)

= 200 = w + 90 × 0.55

= 200 = w + 49.5

= 200 - 49.5 = w

= 150.5 = w

I have got my answer but in approx, hope you will not mind. ^^"

How is a frame of reference used to describe motion
Zinaida [17]
In particle kinematics, we measure the acceleration of the particle. For this, an observer is taken as a reference point. Generally we consider the observer as in origin of a co-ordinate system. The place where observer is placed is known as frame of reference. 
Newton's laws only work in the inertial frame of reference. Inertial frame is a frame of reference whose acceleration is zero. But, if you are observing the motion of an object from non-inertial frame, you need to add and extra force on the system under observation which is known as pseudo force.

Long Shore Drift is the ...
azamat

Answer: D. movement of material along a coast by waves that approach at an angle to the shore.​

Explanation:

Longshore drift is also referred to as the littoral druft and it means the sediment that is moved by the longshore current.

Longshore drift is the movement of material along a coast by waves which approach at an angle to the shore but then recede down the beach.

Therefore, the correct option is D.
