2. The elevator (E) starts from rest and moves upward with a constant acceleration. If the counterweight (W) movesa distance of 32 feet in 4 seconds, determine: A. The acceleration of the elevator, B. The acceleration of point C on the cable, and C. The velocity of the elevator after 4 seconds. E.
A bus starts from rest and accelerates uniformly for 20 seconds to a speed of 18 km/h

A bus starts from rest and accelerates uniformly for 20 seconds to a speed of 18 km/h. It then moves with a uniform velocity and it is finally brought to rest in 100 meteres with a constant retardation. If the total distance travelled is 0.5km. Find the accelration, retartdation and total time taken. My answers are total time = 110s Retardation -1/4ms^-2. Please check if they r correct or not!!!

A speedboat starts from rest with a constant acceleration of +1.50 m/s2. After 4.00 seconds, its acceleration changes to +1.00 m/s2. After another 5.00 seconds, its acceleration changes to zero and the boat travels with constant velocity for a further 10.0 seconds. The boat then slows down and stops by accelerating at -2.00 m/s2. 1. Calculate the velocity and displacement of the boat at t = 4.00 seconds. 2. Calculate the velocity and displacement of the boat at t =...
