unbalanced force is applied to make it move. 2. A bicycle travels at 20 km h-1. along a level road. When a cyclist is travelling at constant speed, forces opposing his motion balance forces moving him forward. The cyclist is in equilibrium and will . continue to travel at the same speed, in the same direction, unless an Take your speed. Multiply the value by 0.62. A handy trick if you don’t have a calculator to hand (e.g., you're driving) is to use the Fibonacci sequence (1, 1, 2, 3, 5, 8…). Take a number, the next one in the sequence is the kilometres if the previous one was miles (e.g., 50 mph is roughly 80 kph).
car? 0.85 m/s 2. Tyrell throws his 0.20-kg football in the living room and knocks over his mother’s 0.80-kg antique vase.

In an elastic collision, a 400-kg bumper car collides directly from behind with a second, identical bumper car that is traveling in the same direction. The initial speed of the leading bumper car is 5.60 m/s and that of the trailing car is 6.00 m/s.
The two cars are moving in same direction with same speed. So let the speed of two cars be v Km/h and velocity of car moving in opposite direction be u Km/h. So, total speed= total distance/ time= 5/1/15 (4 minutes= 4/60= 1/15 hrs.). So we will get total speed as 75 km/h.
A moving van and a small car are traveling in the same direction on a two-lane road. The van is moving at twice the speed of the car and overtakes the car.
