You will need to multiply them.
I have physics class and for acceleration we use 9.8m/s^2 but you used 9.5m/s^2.
If that’s what ur teacher wants u to use that’s ok. But yeah you multiply them.
F=ma
You multiply m and a

Answer:
Newton's first law
Explanation:
it says that an object will continue to be at rest or keep moving till any external for is applied to it to make it move or stop respectively.
Answer:
162 KJ
Explanation:
The electrical energy can be calculated using the formula
E = V×I×t
Where, V= voltage = 120 V
I is current in ampere = 7.5 A and t is time in seconds
1 hour = 3600 sec
Therefore, 0.05 hour = 3600×0.05 = 180 sec
Substitute the values in above equation find electrical power
E = 120×7.5×180
= 162000 J
= 162 KJ
Therefore, the electrical energy use of the microwave = 162 KJ

Answer:The total momentum before collision is equal to the total momentum after collision.</h2>
Explanation:
Conservation of momentum states that whenever no external force is acting on a system,the total momentum is constant.
When we consider collisions,take the system as the two bodies that are colliding.
There are no external forces acting on the system.The forces that one body exerts on other come under internal forces.
So,momentum can be conserved in this case.
So,the total momentum before collision is equal to the total momentum after collision.
