In a motorcycle race, a rider A is leading another rider B by 36 m and both riders are travelling at a constant speed of 170 kph. At t=0 both starts accelerating at a constantrate. It is given that after 8s, So vertakes And at this instant speed of A is 220 kph. Find the accelerations of the two riders

An object, starting with an initial speed and moving at constant acceleration traveIs 150 m in 5 s. The acceleration stops after this and in the next 5 s the object traveIs 200 m farther. Find the initial velocity and acceleration of the object.

In the overhead view of Fig. 4-40, Jeeps P and B race along straight lines, across flat terrain, and past stationary border guard A. Relative to the guard, B travels at a constant speed of 25.0 m/s, at the angle theta_(2)=30.0^(@) . Relative to the guard, P has accelerated from rest at a constant rate of 0.400m//s^(2) at the angle theta_(1)=60.0^(@) . At a certain time during the acceleration, P has a speed of 40.0 m/s. At that time, what are the (a) magnitude and (b) direction of the velocity of P relative to B and the ( c) magnitude and (d) direction of the acceleration of P relative to B?

Two bicycle riders made a 30 km trip in the sametime. Cyclist A travelled non-stop at an average speed of 20 kph. Another cyclist B travelled with a lunch break of 20 min. What was the average speed of B for the actual riding ?

There are two cars on a straight road, marked as x axis. Car A is travelling at a constant speed of V_(A) = 9 m//s . Let the position of the Car A, at time t = 0 , be the origin. Another car B is L = 40 m ahead of car A at t = 0 and starts moving at a constant acceleration of a = 1 m//s^(2) (at t = 0). Consider the length of the two cars to be negligible and treat them as point objects. (a) Plot the position–time (x–t) graph for the two cars on the same graph. The two graphs intersect at two points. Draw conclusion from this. (b) Determine the maximum lead that car A can have.
