An automobile is traveling at \(22.0 \mathrm{~m} / \mathrm{s}\). Find its speed (a) in \(\mathrm{km} / \mathrm{h}\). (b) in \(\mathrm{mi} / \mathrm{h}\). (c) in ft/s.

A mechanic test driving a car that she has just given a tune-up accelerates from rest to \(50.0 \mathrm{~m} / \mathrm{s}\) in \(9.80 \mathrm{~s}\). How far does she travel in that time?

A plane accelerates at \(30.0 \mathrm{ft} / \mathrm{s}^{2}\) for \(3.30 \mathrm{~s}\). Find its increase in speed in \(\mathrm{ft} / \mathrm{s}\).

A bearing rolls off a \(1.40\) -m-high workbench with an initial horizontal speed of \(0.600 \mathrm{~m} / \mathrm{s}\). How far from the edge of the bench does the bearing land?

A rocket lifting off from earth has an average acceleration of \(44.0 \mathrm{ft} / \mathrm{s}^{2}\). Its initial velocity is zero. How far into the atmosphere does it travel during the first \(5.00 \mathrm{~s}\), assuming that it goes straight up?

A plane accelerates at \(30.0 \mathrm{ft} / \mathrm{s}^{2}\) for \(3.30 \mathrm{~s}\). Find its increase in speed in \(\mathrm{mi} / \mathrm{h}\).

A mechanic's socket rolls off a \(1.50\) -m-high bench with an initial horizontal speed of \(0.800 \mathrm{~m} / \mathrm{s}\). How far from the edge of the bench does the socket hit the floor?

A semi-trailer truck traveling \(100 \mathrm{~km} / \mathrm{h}\) continues for \(2.75 \mathrm{~h}\). How far does it go?

The final velocity of a truck is \(74.0 \mathrm{ft} / \mathrm{s}\). If it accelerates at a rate of \(2.00 \mathrm{ft} / \mathrm{s}^{2}\) from an initial velocity of \(5.00 \mathrm{ft} / \mathrm{s}\), how long will it take for it to attain its final velocity?

A rocket accelerates at \(10.0 \mathrm{~m} / \mathrm{s}^{2}\) from rest for \(20.0 \mathrm{~s}\). Find its increase in speed in \(\mathrm{m} / \mathrm{s}\).
