Answer:
B. 2. A baseball was hit by a bat and now flying through the air.
Explanation: A baseball that is hit by a bat has a larger velocity, due to this the amount of kinetic energy is high.
If the acceleration constant..
you can use the formula s = ut + 1/2at²
Known that :
s = ?
u = 0
t = 2s
a = 10ms-²
Then you can apply the formula
s = ut + 1/2at²
s = 0 + 1/2(10)(2)²
s = 5 × 4
s = 20m
Answer : 20m
Explanation :
The gravity can be 9,8 or 10. Also im not sure how people teach you but in my school, if the ball goes down the gravity is positive and not negative thats why i put 10ms-² and not -10ms-²
s = displacement/distance
u = initial speed
a = acceleration
t = time
sorry if im wrong
Answer:
The moment of inertial of the wheel, 
Explanation:
Given;
8 spokes of uniform diameter
mass of each spoke, =
length of each spoke, = L
mass of outer ring, = 
The moment of inertial of the wheel will be calculated as;

where;
is the moment of inertia of each spoke
is the moment of inertia of the rim
Moment of inertia of each spoke 
Moment of inertial of the wheel

Answer:B
