1. F=ma
Here we have an acceleration = 2.3 and a mass = 14
So...
F = (14)(2.3)
F = 32.2 N
2. F = ma
Here we have an acceleration = 6.4 and a force = 1473
Rearrange your equation for m
F/a = m
1473 / 6.4 = m
m = 230.16 kg
3. F = ma
Here we have a force = 94 and a mass = 45
Rearrange for acceleration
F/m = a
94 / 45 = a
a = 2.09 m/s^2
Answer:
1: an object will stay still until acted on by another force
2: acceleration of an object depends on the mass of the object and the force applied
3: for every action there is an equal and opposite reaction
Answer:
a)
b)
Explanation:
a)
Using the conservation of energy between the moment when the bullet hit the block and the maximum compression of the spring.
Where:
- M is the bullet-block mass (0.00535 kg + 2.174 kg = 2.17935 kg)
- V is the speed of the system
- k is the spring constant (6.17*10² N/m)
- Δx is the compression of the spring (0.0634 m)
Then, let's find the initial speed of the bullet-block system.
b)
Using the conservation of momentum we can find the velocity of the bullet.
I hope it helps you!
Answer:
2 a) it is less dense than the water
2 b) it is more dense than the water
3 a ping pong ball is hollow and less dense than the water so it quickly bounces up to the surface of the water
Answer:
Along with protons, neutrons make up the nucleus, held together by the strong force. The neutron is a baryon and is considered to be composed of two down quarks and one up quark. A free neutron will decay with a half-life of about 10.3 minutes but it is stable if combined into a nucleus.
