A bicyclist slow with a force of 3.5 × 10² N. if the bicyclist and bicycle have a total mass of 1.0 × 10² kg, what is the accele

Aleonysh [2.5K]

Answer:

3.5 m/s²

Step-by-step explanation:

We are given;

The force of a bicycle as 3.5 × 10² N
Mass of the bicycle as 1.0 × 10² kg

We are required to determine the acceleration of the bicycle;

From Newton's second law of motion;

F = ma

Rearranging this;

a = F÷ m

Therefore;

Acceleration = 3.5 × 10² N ÷ 1.0 × 10² kg

= 3.5 m/s²

Thus, the acceleration of the bicycle is 3.5 m/s²

A box contains 144 marbles, which are either red or blue. if there are 3 times as many red marbles as there are blue marbles in

kicyunya [14]

Given:
X: The blue marbles.
3X: The red marbles.
A box contains 144 marbles.
SOLVING:
X + 3X = 144
4X = 144
X = $\frac{144}{4}$
X = 36 ===> The blue marbles.

If there are 3 times as many red marbles as there are blue marbles:
3(36) = 108 ===> The red marbles. SOLUTION

TESTING:
$36+108=144$
$\boxed{144}=\boxed{144}\quad\checkmark\ The\ value\ is\ correct.$
GOOD LUCK...!!!

Chao bought a boat for HK$160 000

Dennis_Churaev [7]

Answer:

$141,557.76

Step-by-step explanation:

Chao bought a boat for 160,000

The value of the boat reduces by 4% every year

Therefore the value of the most at the end of three years can be calculated as follows

= 100%- 4%

= 96%

= 160,000 × 96/100^3

= 160,000 × 0.96^3

= 160,000 × 0.884736

= 141,557.76

Hence the price of the boat after 3 years is 141,557.76
