Q. A seed shoots out from the pod with the speed of 2.6 m/s but with a direction of motion 30° below the horizontal. The seed pod is initially 1.1 m above the ground.
How long does it take for the seed to land? (Neglect air resistance.)
What horizontal distance does it cover during its flight?
what is the minimum coefficient of static friction required between tires and race track if the car is to stay on the track at a speed of 130m/s.
Calculate the magnitude, the direction of resultant force and the coefficient of kinetic friction.
A small turtle moves at a speed of 165 furlongs per fortnight. Find out the speed of the turtle in centimeters per second. Note that 1 furlong = 220 yards and 1 fortnight = 14 days.
