Answer:
<em>( About ) 1.77 seconds; Option B</em>
Step-by-step explanation:
We are given the equation h ( t ) = - 16t^2 + 50, so in order to determine the time let us determine the x - intercept for y ⇒ 0;
- 16t^2 + 50 = 0,
- 16t^2 = - 50,
t^2 = 25 / 8,
Thus t ⇒ √ ( 25 / 8 ), and t ⇒ - √ ( 25 / 8 ),
t ⇒ ( 5√2 )/ 4, and - ( 5√2 )/ 4,
But time is represented only by a positive value, thus
t ⇒ ( 5√2 )/ 4 = 1.767766953......., ( About ) 1.77 seconds

Answer:
Step-by-step explanation:
It can be solved by applying formula for Force.
Force = mass * acceleration
Unit of force is N(newton)
one newton is the force applied on body when a body of mass one kg, accelerate at 1/ms^2 under the influence of force.
________________________
given
Mass = 5 kg
acceleration = 6/ms2
plug in the value of mass and acceleration in formula for for we have

Thus 30 N(newton) force is required to accelerate at 6m/s^2
