Answer:
Explanation:
a ) Velocity vs time graph will be a straight line with negative slope , making a slope of 2 because slope of v-t graph gives the value of acceleration.
b ) v = 0 , u = 28 m/s
t = ?
v = u - at
0 = 28 - 2 t
t = 14 s
shuttle velocity will become zero after 14 sec.
c ) v ² = u² - 2 a s
0 = 28² - 2 x 2 x s
s = 28² / 4
= 196 m .

Explanation:
b. seismic waves need a medium for propagation.
Explanation:
Fnet = 12.0N - 5.0N = 7.0N
a = Fnet/m = 7.0N/6.5kg = 1.07m/s².
