a 7.0 kg ball is attached to a rope that forces the ball to travel along a circular path the Rope is 3.4 meters in length and has a rotational speed of 4.2 rad/s. calculate the centripetal force.​

When a 5.0kg cart undergoes a 2.2m/s increase in speed, what is the impulse of the cart

How are calculation for velocity and speed different

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?
