Answer: 37.5 kg in 3 s.f.
Explanation:
Answer:
7.6427m/s
Explanation:
Given:
#Applying the conservation of momentum along the x-axis:
#And along y-axis:

#Solving for
:

#By substitution in the x-axis equation:

Hence the original speed of the ball before impact is 7.6427m/s

C Or D
Explanation:
The Child Should Get Checked On Before You Call The Police Thought,
Answer:
a=8.1832m/s^2
Explanation:
Vo=initial speed=0m/s
Vf=final speed=26.8m/s
t=time=3.275s
the vehicle moves with a constant acceleration therefore we can use the following equation
A=aceleration=(Vf-Vi)/t
A=(26.8m/s-0m/s)/3.275s=8.1832m/s^2
the magnitude of the car´s aceleration is 8.1832m/s^2
