Question

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 speed of 35m/s. what is the acceleration

Answer 1

Answer:

The acceleration is 2.9m/s^2

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

$a = 29/10$

$a = 2.9$

Hence, the acceleration is 2.9m/s^2
