Which describes an object in projectile motion? Select three options.
Karo-lina-s [1.5K]

Description of an object in projectile motion is;

  • Gravity acts to pull the object down.
  • The object’s inertia carries it forward.
  • The path of the object is curved.

Explanation:

The path of the projectile is usually curved, and NOT straight, due to the influence of gravity on it which is teh only force acting on it-, causing it motion path to fall towards the earth. Most projectiles follow a parabolic path. The projectile, even though it was launched, its motion is then only due to its own inertia – tendency to stay in motion in a straight line, or rest, unless an external force is acting on it - such as drag or friction.  An example of such projectile motion is of ballistic missiles.

A 107 gram apple falls from a branch that is 2 meters above the ground. (a) How much time elapses before the apple hits the grou
andreev551 [17]

Answer:

The time of motion is 0.64 s.

Explanation:

Given;

mass of the apple, m = 107 g

height of fall, h = 2 m

The velocity of the apple when it hits the ground is calculated from the law of conservation of energy;

P.E = K.E\\\\mgh = \frac{1}{2} mv^2\\\\gh = \frac{1}{2} v^2\\\\v^2 = 2gh\\\\v = \sqrt{2gh} \\\\v = \sqrt{2\times 9.8\times 2} \\\\v = 6.261 \ m / s

The time of motion is calculated;

v = u + gt

6.261 = 0 + 9.8t

6.261 = 9.8t

t = 6.261 / 9.8

t = 0.64 s

Therefore, the time of motion is 0.64 s

Pepsi [2]

Answer:

v = 10.89\ m/s

Explanation:

given,                          

radius of loop = 12.1 m                              

to find the minimum speed transverse by the rider to not to fall out upside down                                                                

centripetal force = \dfrac{mv^2}{r}

gravitational force  = m g

computing both the equation]

mg = \dfrac{mv^2}{r}

v = \sqrt{rg}

v = \sqrt{12.1 \times 9.8}

v = \sqrt{118.58}

v = 10.89\ m/s
