A car driver leaves Bangalore at 8.30 A.M. and expects to reach a place 300 km from Bangalore at 12.30 P.M. At 10.30 he finds that he has covered only 40% of the distance. By how much he has to increase the speed of the car in order to keep up his schedule?

A motorbike is travelling at 30m/s on a motorway. If the bike must stop in 5s, what will be the acceleration of the motorbike?

A BMX rider is coming up to a ramp that is set to 10.0° and the end point is 1.70 m above the ground. They travel up the ramp at a steady speed of 7.90 m/s. What speed will they have just before they hit the ground?

A jogger (60 kg) is running 3 m/s down the road.  What is his kinetic energy?

A stuntman drives a dirt bike on a curved track with a radius of 16.9 m. If he starts from rest and accelerates at 1.06 m/s2, at what time will the magnitude of the total acceleration of the bike be 5.74 m/s2? (Hint: the tangential acceleration will stay constant at 1.06 m/s2.)
