Explanation:
gradpoint
Answer:
I think it's B it can not be C or D because it has nothing to do with chemical energy
Answer:
Your answer is B
Explanation:
When a ball falls it is gaining kinetic energy because it gains speed as it falls.Since its gaining kinetic energy it loses potential energy so ur answer is B :) hope it helps
Answer: 1.81m
Explanation:
Given the following:
Horizontal speed = 4m/s
Height of table = 1m
Taking the vertical component of the motion:
Using:
S = ut + 0.5 at^2
Where, S = height of table, a = acceleration due to gravity (9.8m/s^2), t = time and u = Initial Velocity in vertical direction = 0
1 = 0(t) + 0.5(9.8)t^2
1 = 4.9t^2
t^2 = 1 / 4.9
t^2 = 0.204081
t = sqrt(0.204081)
t = 0.452s
For Horizontal :
Gravitational acceleration is absent, therefore distance can be calculated using:
Distance = Velocity × time
Distance = 4m/s × 0.452s
Distance = 1.808 m
Distance = 1.81m
