A roller coaster ride in a park includes a vertical drop of 60 m. Assume that the roller coaster has a speed of nearly zero when it reaches the top of the hill. Neglecting friction, find the speed of the riders at the bottom of the hill
A student has designed his own thermometer with a temperature scale called S. Here
he has marked the freezing point of water as 30 °S and the boiling point of water as
150 °S. The S scale has 130 divisions.
(a) By drawing a suitable diagram, express the relation (mathematical equation)
between 𝑇𝐶 (temperature in Celsius) and 𝑇𝑆 (temperature in S)
(b) What reading will be shown in S scale when he measures the temperature of an
object at 60°C.
town B is 1124 km north of city A, an airplane that can travel at 765 km/h in still air departs city A and plans to fly in a straight line to city B, despite wind blowing at 65.6 km/h W. The magnitude of the planes velocity relative to the ground is?
