The acceleration of the body is determined by differentiating the velocity, and velocity by differentiating the displacement. By doing the reverse, we integrate the acceleration to get the velocity and integrate the velocity to get the displacement.
velocity = 20v^-3 and displacement = (20/3)v^-2
Substituting the value of v,
velocity = 20/(2 m/s)^3 = 2.5 m/s
displacement = 20/3 / (2m/s)² = 5/3 m
Answer:
10 seconds.
Explanation:
We can use a kinematic equation where we know the final velocity, initial velocity, acceleration, and need to determine the time <em>t: </em>
<em /><em />
<em />
The initial velocit is 30 m/s, the final velocity is 0 m/s (as we stopped), and the acceleration is -3 m/s².
Substitute and solve for <em>t: </em>

Hence, it will take the car 10 seconds to come to a stop.
Answer:
a) 1074.27 km
b)
c) 477.453 km/h
d) 638.22 km/h
Explanation:
From Pythagoras theorem
AC² = AB²+BC²
Displacement = 1074.27 km
Direction =
Average velocity
Average velocity = 477.453 km/h
Average speed
Average speed = 638.22 km/h
