Question

a body is moving in a straight line x is equal to 4 cos(t) m find the displacement 0 to pi by 2 seconds​

Answer 1

Answer:

21 In a car race, Car A takes t second less than Car B

at the finish and passes the finishing line with 5.5 m/s more than that Car B. Assuming that

both cars start from rest and travel with constant

acceleration 2m/s2 and 1 m/s2 respectively, then

value of tis (in second unit)21 In a car race, Car A takes t second less than Car B
