Answer:
1000 Kilograms
Explanation:
Force is equal to mass times acceleration so if the force is 3000 and the acceleration is 3 m/s^2 then all you need to do to find the mass is divide 3000 by 3 which gives you 1000
This is reactivity. It describes how easily one substance reacts with another
Answer:
180 m
Explanation:
Given:
Uniform speed of the car, U = 30 m/s
Uniform acceleration of the motorcycle = 10 m/s²
For the motorcycle to catch up with the car, the distance traveled must be the same.
For the car;
Distance = Speed × Time
⇒ d = u × t
d = 30 × t
d = 30t ......(1)
For the motorcycle;
The stationary police motorcycle has initial speed, u = 0
From equation of motion;
but u = 0
.....(2)
Equating equation (1) and (2)
30t = 5t²
t = 6 seconds
Substituting t = 6 s into equation (2)
d = 5(6)²
d = 5 × 36
d = 180 m
The motorcycle must travel 180 m before it catches up to the car
Frequency is indirectly proportional to the wavelength, in other words, when frequency increases wavelength decreases and vice-versa
c = ∧f
Hope this helps!
