Answer:
speed-time graph is the acceleration of the particle or straight lines acceleration is constant
a distance-time graph represents that a particle has constant speed.
Explanation:
Answer:
24.531 m
Explanation:
t = Time taken = 1.7 s
u = Initial velocity = 6.1 m/s
v = Final velocity
s = Displacement
g = Acceleration due to gravity = 9.81 m/s² = a
Equation of motion

The initial height of the rock above the ground is 24.531 m
