What is the best term used to describe a vehicle hitting another object?

One chef places a pie in the oven at a low setting so that it is baked in one hour. Another chief place a pie in the oven at a h

KengaRu [80]

In each case, (the pie in a low setting at one hour versus the pie in a high setting at thirty minutes) the amount of energy is the same. However, the amount of power is different. Since power is the amount of work put in certain amount of time, the power in the high setting is larger compared to the power in the low setting.

A policeman, parked at arn intersection, is passed by a speeder traveling at 120 km/hr. Two seconds later, the policeman starts

pashok25 [27]

Answer:

682.32 m

Explanation:

Speed of the passing speeder = 120 km/hr = 120 × 0.2777 = 33.33 m/s

time after which police man starts = 2 seconds

Acceleration of the policeman = 4.0 m/s²

let the time taken to catch be 't' seconds

Now,

The total distance to be covered by the policeman

= Distance covered by the speeder in the 2 seconds + Distance further traveled by the speeder in time t

thus,

From Newton's equation of motion

$s=ut+\frac{1}{2}at^2$

where,

s is the total distance traveled by the police man

u is the initial speed = 0

a is the acceleration

t is the time

thus,

$0\times t+\frac{1}{2}\times4t^2$ = 33.33 × 2 + 33.33 × t

or

2t² = 66.66 + 33.33t

or

2t² - 33.33t - 66.66 = 0

on solving the above equation, we get

t = 18.47 seconds (negative value is ignored as time cannot be negative)

therefore,

the total distance covered = 33.33 × 2 + 33.33 × 18.47 = 682.32 m
