Answer:
Explanation:
Given that,
Initial speed of the car, u = 14 m/s
Finally, it comes to rest, v = 0
Time, t = 5.6 s
We need to find the average acceleration of the car during this time interval. We know that,
So, the acceleration of the car is in the opposite direction of motion.
Answer:
Explanation:
Given that,
Mass of astronaut
M = 62kg
Mass of wrench
m = 3.3kg
Speed at which wrench move away from the capsule
v = 20.5m/s
Speed of astronaut?
Let speed of astronaut be V
Since there is no external force, we would apply conservation of momentum
Momentum of the astronaut is equal to the momentum of the wrench
Momentum is given as
P = Mass × Velocity
P(astronaut) = P(wrench)
M×V = m×v
V = m×v/M
V = 3.3×20.5/62
V = 1.09 m/s
The astronaut speed is 1.09m/s
When a person is making cardiovascular gains through aerobic activity they are increasing the amount of oxygen to the heart and lungs. This keeps the heart and lungs of a person very healthy. It decreases the chance of heart diseases.
Answer:
<h2>537.6 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 84 × 6.4
We have the final answer as
<h3>537.6 N</h3>
