Running and stopping without slipping and cars accelereating
A solution is a value or a collection of values.. when substituted for the unknowns, the equation become an equality.
Example : x + 2 = 7
When we out the 5 in place of x we get: 5 + 2 = 2
Answer:
The answer is 1100kg.
Explanation:
First, you have to find the acceleration using the formula, a = (v-u)/t where v is final speed, u is initial speed and t is time :
Next, you have to apply force formula, F = m×a where m is mass :
