Which of the following is not an example of acceleration? A.) A bird, flying at a speed of 5 m/s, speeds up to 10 m/s in a constant direction of north

B.) A car travels along a straight section of highway at a constant 100 km/h

C.) A person runs at a constant 3 mi/h while turning from the north to the east

D.) A car travels along a curve while slowing down to 60 km/h from 100 km/h

Given the position vector of the particle r(t)=(t+1)i+(t^2−1)j+2t k, find the particle's velocity and acceleration vectors at t=1

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?

You are given two vectors a⃗ =−3.00ι^ 5.00j^ and b⃗ =5.00ι^ 2.00j^. let the counterclockwise angles be positive.
