Answer:

A) Energy is dissipated into heat and sound energy due to Friction

B) The energy goes into heat and sound energy due to friction again, otherwise the cart would accelerate due to an unbalanced force. Therefore, we know there's friction, and the friction causes energy loss.

A projectile is shot on level ground with a
erastova [34]

Answer:

time rising = 34 / 9.8 = 3.47 sec

total time in air = 2 * 3.47 sec = 6.94 sec

(time rising must equal time falling)

R = 17 m/s * 6.94 s = 118 m

Can also use range formula

R = v^2 sin (2 theta) / g

tan theta = 34 / 17 = 2

theta = 63.4 deg

2 theta = 126.9 deg

sin 126.9 = .8

v^2 = 17^2 + 34^2 = 1445 m^2/s^2

R = 1445 * .8 / 9.8 = 118 m    agreeing with answer found above

answer key to Student Exploration: Feed the Monkey (Projectile Motion) page 3 Activity B Question: As the banana flies through s
murzikaleks [220]

As the banana flies through space, up the red arrow showing its path of motion takes a curved or parabolic shape.

<h3>What is a projectile?</h3>

A projectile is an object launched into space at an angle to the horizontal ground and allowed to fall freely under gravity.

The path of motion of a projectile is parabolic.

Examples of objects that are projectiles include:

  • A thrown banana
  • A kicked football
  • An arrow shot from a bow

Therefore, as the banana flies through space, up the red arrow showing its path of motion takes a curved or parabolic shape.
