<u>Given data:</u>
acceleration (a) = 1.5 m/s² ,
mass (m) = 1800 Kg ,
Determine F = ?
<em>From Newtons II law</em>
F = m.a N
= 1800× 1.5
= 2700 N
<em>2700 N force needed to accelerate the car</em>
Answer:
5595 m
Explanation:
The wave travels down (the depth) and the back up (the depth again)
this distance is 2 d
2 d = 1492 m/s * 7.5 s
2d = 11190 m
d = 5595 m
Answer:
A lightning conductor is made up of a sharp pointed metal (usually copper metal, as it is a very good conductor) connected directly to the ground. ... The lightning conductor is placed higher than the roof so that if lightning strikes, it strikes the conductor before it can reach the house.

Answer:
0 N
Explanation:
According to Newton's first law of motion, an object in motion stays in motion until acted upon by an unbalanced force. With no friction in space to unbalance the cannonball, it will continue to keep going.
Answer:
750 J
Explanation:
lets convert mass into kg first , 150 /1000 = 0.15 kg
kinetic energy = 
=
