Answer:
total time = 65 seconds
total distance = 1554 meters
Explanation:
kinematic equation:
final velocity = initial velocity + acceleration multiplied by time
v_1 = v_0 + at
28 m/s = 0 m/s + 2 m/s^2 (t)
t = 14 seconds
a) total time = 14 + 46 + 5 = 65 seconds
b) must solve for total distance and divide it by time.
d_1 = v_0t + 1/2 a * t^2
d_1 = 0 + 0.5(2) * 14^2
d_1 = 196 meters
d2 = vt
d2 = 28 *46
d2 = 1288 meters
v_1 = v_o + at
0 = 28 + a(5)
- 28/5 = a
a = - 5.6 m/s^2
d_3 = v_0t + 1/2 a * t^2
d_3 = 28 (5) - 0.5(5.6)*5^2
d_3 = 70 meters
total distance = d1 + d2 + d3 = 196 + 1288 + 70 = 1554 meters
The x-component of Anne's path:
80 x cos(33)
= 67.1 meters
y-component of Anne's path:
80 x sin(33)
= 43.6 meters
To draw he diagram, you draw a horizontal line starting at point 1 to the right representing 67.1 meters. At the end of this line, draw a vertical line upwards representing 43.6 meters.
Connect the start of the horizontal line at point 1 to the end of the vertical line with an angle of 33° between them.
Most likely the baseball because it weighs less therefore with the same force it will go further due to the fact it weighs less it would be easier to apply force and the less it weighs there is also less force acting upon it.
The cats have full bowls in the morning and afternoon, Katy can assume that the cats do not eat in the morning or afternoon. The bowls are replenished in the evening, which suggests that they become empty in the evening, which suggest that the pattern is that the cats eat in the evening so your answer would be C. Hope this helps. ;)
