A car is traveling on a straight stretch of roadway, and the speed of the car is increasing at a constant rate. At time 0 seconds, the speed of the car is v0 meters per second; 10 seconds later, the front bumper of the car has traveled 125 meters and the
A bust traveling along a straight highway covers one third of the total distance between two plces with a velocity20mkmh−1. The remaining part of the distance was coverd with a velocity of30kmh−1for the first half of the remaining time and with velocity50kmh−1for the next half...
A car is moving along a straight (OP). It moves fromO→Pin18secondsamd retuns fromP→Qin 6 seconds,whereOP=360 mandOQ=240 m What are the car the average velcoty and average speed of the car in going (a) fromO→Pand back toQ?
4 A car travels along a straight road with constant acceleration. It passes through points P, Q, R and S. The times taken for the car to travel from P to Q, Q to R and R to S are each equal to 10s. The distance QR is 1.5 times the distance PQ. At point Q the speed of th...
