I dont get why its c i dont under the graph for the vertical component in option c
jek_recluse [69]
The vertical component grows at an increasing rate because
gravity is ACCELERATING the object vertically.  So its speed
keeps growing.  Speed is the slope of the displacement graph.

Aunt Matilda goes to a well and throws a penny straight down the well at 3.0 m/s. She hears a splash after 0.5 seconds. How deep
nevsk [136]

Answer : The correct option is (d) 2.73 m

Explanation :

By the 2nd equation of motion,

s=ut+\frac{1}{2}at^2

where,

s = distance or height = ?

u = initial velocity  = 3.0 m/s

t = time = 0.5 s

a = acceleration due to gravity = 9.8m/s^2

Now put all the given values in the above equation, we get:

s=(3.0m/s)\times (0.5s)+\frac{1}{2}\times (9.8m/s^2)\times (0.5s)^2

s=2.73m

Therefore, the correct option is (d) 2.73 m

How do you find the acceleration of an object?
artcher [175]
Rearrange the equation F = ma to solve for acceleration<span>. You can change this formula around to solve for </span>acceleration<span> by dividing both sides by the mass, so: a = F/m. To find the </span>acceleration<span>, simply divide the force by the mass of the </span>object <span>being accelerated.

Hope i helped :)</span>
