A motorbike accelerates from 15m/s to 25m/s in 15 seconds.

RSB [31]

distance traveled by a uniformly accelerated bike is given as

$d = \frac{v_f + v_i}{2} (t)$

here we know that

$v_f = 25 m/s$

$v_i = 15 m/s$

$t = 15 s$

now we will have from above equation

$d = \frac{15 + 25}{2} (15)$

$d = 20 (15) = 300 m$

so it will cover the total distance of 300 m

One day you are driving your friends around town and you drive quickly around a corner without slowing down. You are going at a

Novay_Z [31]

Answer:

1.60 g

Explanation:

From the attached file below:

we can deduce that:

$v = v_x =v_y = 20 \ m/s \\t = 2s$

The distance traveled by 2 s will be:

x = vt

x = 20 m/s × 2 s

x = 40 m

The length is quarter of the circle with radius r,

so; if 2 πr = 4 x

Then radius (r) will be:

$r = \frac{4x}{2 \pi}\\\\r = \frac{4*40}{2 \pi}$

r = 25.5 m

The centripetal acceleration can be expressed as:

$a = \frac{v^2}{r}$

so;

$a = \frac{(20 \ m/s^2)}{25.5 \ m}$

a = 15.7 m/s²

the magnitude of the acceleration experienced by your unfortunate passengers in terms of acceleration due to gravity is then determined by the equation:

$a' = \frac{a}{g} g$

$a' = \frac{15.7 \m/s ^2}{9.81 \ m/s^2}\ g$

$a' = 1.60 \ g$

∴ The magnitude of the acceleration experienced by your unfortunate passengers during the turn = 1.60 g

A sample of the mineral calcite has a volume of 15 cm³ and a mass of 40.5 g. What is the density of the calcite?A.0.37 g/cm³B.2.

maxonik [38]

Given data:

Volume of calcite (V) = 15 cm³,

mass of calcite (m) = 40.5 g,

find the

density of calcite (ρ) = ?

density is defined as " it is the amount of matter of an object in a given volume". Simply it is the ratio of matter in an object to its volume. The unit of density is kg/m³ in SI system or g/cm³ in CGS system.

Mathematically,

density ( ρ) = mass/volume

= m/V g/cm³

= 40.5 g/15 cm³

= 2.7 g/cm³

Hence, the density of calcite is <em>2.7 g/cm³ </em>

An object is moving to the left

dybincka [34]

The object is moving with constant speed means there is no change in speed Hence the acceleration is 0

Where, u is initial speed,

v is final speed

t is time taken and

a is acceleration

a = ( v-u) /t

a =(0)/t because u=v

a=0

Therefore, Acceleration is 0
