Riding his bike, dewayne can start from rest and get going at 12m/s in 4 seconds. beth can get going 16m/s in 5 seconds. who has a greater acceleration? how do you know?

The acceleration of Beth is more than the acceleration of Dewayne.

Explanation:

Acceleration is defined as the rate of change of velocity with respect to time.

Mathematically,

where,

v = final velocity

u = initial velocity

t = time taken

We are given:

Putting values in above equation, we get:

Acceleration of Dewayne =

We are given:

Putting values in above equation, we get:

Acceleration of Beth =

Hence, the acceleration of Beth is more than the acceleration of Dewayne.

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic

explanation: i cant explain. it's difficult to explain.
