A powerful motorcycle can accelerate from rest to 24.8 m/s (55 mi/h) in only 5.90 s. (a) What is its average acceleration in m/s
mel-nik [20]

Answer

given,

initial speed,u = 0 m/s

final speed,v = 24.8 m/s

time, t= 5.9 s

a) acceleration,

a=\dfrac{v-u}{t}

a=\dfrac{24.8 - 0}{5.9}

     a = 4.20 m/s²

b) distance to travel in that time

using equation of motion

   v² = u² + 2 as

   24.8² = 0² + 2 x 4.20 x s

       8.4 s = 615.04

          s = 73.22 m

the motorcycle will travel 73.22 m

A rock is dropped from a tall bridge and hits the water below in 2.9
Ahat [919]

Answer:

The height of the bridge is 14.5

Explanation:

Given the following data

t = 2.9 seconds

g = +10m/s^2

Using the below formula

H = ut + 1/2gt^2

Since the initial velocity u = 0

Then, H = 1/2gt^2

H = 1/2 x 2.9 x 10

H = 2.9 x 10 / 2

H = 2.9 x 5

H = 14.5
