I think i used calulater and it gives me 47.5
Answer:
A to B is in constant speed. b to c is speeding up. c to d is not moving. d to e is slowing down.
Explanation:
a to b is at a constant rate of acceleration. (It is speed up but it is doing it consistantly) The line is curving upwards means it is speeding up just not consistantly like a to b. c to d is not going up or down which means it is not in motion. d to e is slowing down because the line curvs down ward.
Answer:
<h2>The answer is 186 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
<h3>force = mass × acceleration</h3>
From the question
mass = 62 kg
acceleration = 3 m/s²
We have the final answer as
force = 62 × 3
We have the final answer as
<h3>186 N</h3>
Hope this helps you
Answer:
a) 482.5N
b) 17.4N
Explanation:
40 rev/min = 40 * 2π / 60 = 4.2 rad/s
3 rev/min = 3 * 2π / 60 = 0.314 rad/s
