What does a 1kg pineapple weigh on Mars if 3397000m is its radius, and 6.42x10^23 kg is its mass?
2. An automobile rounds a curve of radius 75.0m on a flat road at a speed of 24m/s. What centripetal acceleration is necessary to keep the car on the curve?
3. The fastest human footspeed record is by Usain Bolt at 44.64 m/s. What centripetal force would be needed for him to maintain this speed around the curve of the track if the curve has a radius of 36.5 m and his mass is 94 kg?
