[b]1. In tests on Earth a lunar surface exploration vehicle (mass = 5.68 × 103 kg) achieves a forward acceleration of 0.220 m/s2. To achieve this same acceleration on the moon, the vehicle's engines must produce a drive force of 1.42 × 103 N. What is the magnitude of the frictional force that...

[b]1. A projectile is fired from a gun (on the ground)and has initial horizontal and vertical components of velocity equal to 30 m/s and 40 m/s, respectively.a) How long does it take the projectile to reach the highest point on the trajectory? b) What is the magnitude of the projectile's...
