- The bullet can travel about distance of (2115 m)
- Velocity can be regarded as the ratio of distance to time
- Velocity= (distance / time)
Given: velocity= 450 m/s
Time= 4.7s
- Distance= ( velocity × time)
<em>If we substitute the values</em>
= 2115 m
Therefore, the bullet can travel about 2115 m

Answer to your question:
0.5 m/ s2
The force applied is 47.3 N
Explanation:
First of all, we start by calculating the acceleration of Hailey, which is given by
where:
v = 3.5 m/s is the final velocity
u = 2 m/s is the initial velocity
t = 2 s is the time elapsed
Substituting, we find the acceleration:
Now we can find the force applied by using Newton's second law:
where
F is the force applied
m = 63 kg is the mass of Hailey+the skate
is the acceleration
Substituting, we find the force:

Answer:
14.0 cm
Explanation:
Draw a free body diagram of the block. There are three forces: weight force mg pulling down, elastic force k∆L pulling down, and buoyancy ρVg pushing up.
Sum of forces in the y direction:
∑F = ma
ρVg − mg − k∆L = 0
(1000 kg/m³) (4.63 kg / 648 kg/m³) (9.8 m/s²) − (4.63 kg) (9.8 m/s²) − (176 N/m) ∆L = 0
∆L = 0.140 m
∆L = 14.0 cm
