<h3>
Answer:</h3>
1.5 m/s²
<h3>
Explanation:</h3>
We are given;
Force as 60 N
Mass of the Cart as 40 kg
We are required to calculate the acceleration of the cart.
- From the newton's second law of motion, the rate of change in momentum is directly proportional to the resultant force.
- That is, F = ma , where m is the mass and a is the acceleration
Rearranging the formula we can calculate acceleration, a
a = F ÷ m
= 60 N ÷ 40 kg
= 1.5 m/s²
Therefore, the acceleration of the cart is 1.5 m/s²
FORMULA:
ANSWER:
We are given with mass of car 394kg and velocity of car 15m/s.
Plugging the respective value,
- K.E. = 1/2 × 394 × 15²
- K.E. = 197 × 225
- K.E. = 44,325J
Assuming that the solid being referred to is opaque, it will form a
shadow because it is not able to pass fully through it. If the light is
able to to move through the solid completely, it means that the solid is
transparent, or if only slightly through it, the solid is translucent.
Anything that's moving in a straight line at a constant speed has zero acceleration, and that tells us that there is zero net force acting on it.
