Question

The displacement of a car is given by
X(t)=a1+a2t+a3t2
Where a1=100ft,a2=-88ft/s, and a3=10ft/s2

What is car’s speed at t=2s?
What is the car’s acceleration at t=10s?

Answer 1

OK, can you put the given values of \(a_1 , a_2, a_3\) in the equation of X(t) ?

Answer 2

car's spped will be differentiate x wrt to t and double differentiate wrt t to get acceleration

Answer 3

@maseeullah please reply.

Answer 4

yes if i put then what ?
