Question

In an adventure sport tournament, if a car jumps in proportion to a ratio C which is given
by speed of the car in Kms per hour / weight of the car in Kgs and a car weighing 1825 kg
running at a speed of 91.25 Kms per hour jumps 62.5 meters, how much speed would be
required by a car weighing 1000Kgs to jump the same distance Calculate! [5]​

Answer 2

The speed required by a car of weight 1000 kg to jump the same distance is 50 km/h.

Given:

Speed of car A = 91.25 Km/h

Weight of car A = 1825 kg

Weight of car B = 1000 kg

To find:

Speed of car B to jump the same distance as car A.

Solution:

Jumping distance is given proportional to the ratio

$C = \frac{v}{w}$

• Where v = speed of the car
• Where w = weight of the car

Therefore for the jumping distance to be the same, the ratio C of car A and car B should be the same.

$C_{a} = \frac{91.25}{1825}$

$C_{b} = \frac{v}{1000}$

We have to find v which is the speed of car B.

$\frac{91.25}{1825} = \frac{v}{1000}$

$v = 50 km/h$

Hence the answer is 50 km/h.
