A roller coaster is going down the slope and the speed is 6m/s . 10 seconds later it has reached the bottom of the slope with a
weqwewe [10]

Answer:

The acceleration is 2.9m/s^2

<em></em>

Step-by-step explanation:

Given

Initial\ Speed\ (u) = 6m/s

Final\ Speed\ (v) = 35m/s

Time\ (t) = 10s

Required

Determine the acceleration

This question will be answered using Newton's first equation of motion.

v = u + at

Substitute values for v, u and t

35 = 6 + 10 * a

35 = 6 + 10 a

Collect Like Terms

10a = 35-6

10a = 29

Solve for a

a = 29/10

a = 2.9

<em>Hence, the acceleration is 2.9m/s^2</em>

The volume of this right circular cylinder is 64π cubic yards. If h, the height of the cylinder, is 4 yards, what is r, the radi
sergiy2304 [10]

Answer:

h = 4 cm

Step-by-step explanation:

The formula for volume of a cylinder is

V = πr²h      where V is the volume, r is the radius, and h is the height.

We are given V = 64π, and r = 4, plug those in and solve for h

64π = π(4²)h

64π = 16πh

(64π)/(16π) = (16πh)/(16π)      (divide both sides by 16π)

4 = (16π)/(16π)h

 4 = h
