Answer:
300 N
Explanation:
The net force acting on the arrow is given by Newton's Second Law:
where
m = 0.06 kg is the mass of the arrow
a = 5,000 m/s^2 is the acceleration of the arrow
Substituting the numbers into the equation, we find

Answer:
5.9 m
Explanation:
v=6m/s
H=5m
h=0.17m
g=10 m/s
First we find the time in which ball reaches the entrance of coffee can. For this purpose the ball has to travel a distance S vertically downward such that
S= 5-0.17 = 4.83 m
While falling down Vi =0
g= 10 m/sec2
t = ?
S=vit+1/2 gt2
==> 4.83=0+0.5×10×
==> 4.83=5×
==> =4.83/5 = 0.97
==> t= 0.98 sec
So in this time the ball reaches the coffee can height level. Now let's calculate horizontal distance covered by the ball in this time.
Horizontal distance = horizantal velocity × time
= 6 × 0.98 = 5.9 m
Answer:
(A). The magnitude of the momentum of the marble is 0.004745 kg m/s.
(B). The speed of baseball is 23.0 m/s
Explanation:
Given that,
Mass of marble = 0.0073 kg
Speed = 0.65 m/s
(A). We need to calculate the magnitude of the momentum of the marble
Using formula of momentum
Where, m = mass
v = velocity
Put the value into the formula
(B). Mass of baseball = 0.136 kg
Momentum of baseball = 3.14 kg m/s
We need to calculate the speed of baseball
Using formula of momentum
Put the value into the formula
Hence, (A). The magnitude of the momentum of the marble is 0.004745 kg m/s.
(B). The speed of baseball is 23.0 m/s
