Cars are designed to decelerate passengers over a certain distance. This allows part of the impact to be absorbed in case of a collision. A crash test dummy is in a car traveling at an initial velocity of 21 m/s. The car slams into a brick wall, bringing it to rest at a constant rate of deceleration. If the time between the moment of impact and the moment the crash test dummy comes to rest is 0.3 seconds, how far has the crash test dummy traveled in this time?

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?
