<span>The value of the constant needed to complete in joules to three significant figures is 2.18 x 10^-18 J.</span>
As per kinematics equation we are given that
now we are given that
a = 2.55 m/s^2
now we need to find x
from above equation we have
so it will cover a distance of 93.2 m
Answer:
C. An ion with a +2 charge
Explanation:
I guess
Answer:
No they are totally different...
Velocity is displacement/time. while vector is both magnitude and direction.....
Velocity is a vector quantity because it has both magnitude and direction
Answer:
11.8 m/s
Explanation:
At the top of the hill, there are two forces on the car: weight force pulling down (towards the center of the circle), and normal force pushing up (away from the center of the circle).
Sum of forces in the centripetal direction:
∑F = ma
mg − N = m v²/r
At the maximum speed, the normal force is 0.
mg = m v²/r
g = v²/r
v = √(gr)
v = √(9.8 m/s² × 14.2 m)
v = 11.8 m/s
