A tow truck exerts a force of 3000 N on a car, accelerating it at 2 m/s2. What is the mass of the car?
2 answers:
The answer is <span>C. 3000 kg.</span>
Answer:
Mass, m = 1500 kg
Explanation:
Given that,
Force acting on the truck, F = 3000 N
Acceleration of the truck, 
Let m is the mass of the truck. It can be calculated using second equation of motion as
F = m × a
m = 1500 kg
So, the mass of the truck is 1500 kg. Hence, this is the required solution.

Alot as far as i know unless you need it in formal terms.
D. 980, this is the best answer because 35 x 7 is 980 :)
F = G*((m sub 1*m sub 2)/r^2)
Its C) refraction
hope its may help you
Answer:

Explanation:
Given that
a= 8 cm (square)
A= a ² = 64 cm²
d= 4.2 mm
d₁= 2.1 mm ,K₁= 4.7
d₂=2.1 mm , K₂=2.6
