A 1000 kg race car starts from rest and reaches a speed of 100 km/h in 20 s. What is the power delivered by the car’s engine? (2 points). A 1 kg mass is released from the top of a smooth slide of height 2m. At the bottom of the slide the mass slides on a horizontal surface and stops at a distance of 5 m. What is the coefficient of kinetic friction of the horizontal surface? (3.5 points). The...

A car that weighs 1.4×104 N is initially moving at a speed of 50 km/h when the brakes are applied and the car is brought to a stop in 15 m. Assuming that the force that stops the car is constant, find the magnitude of that force. Incorrect. Tries 5/20 Previous Tries Find the time required for the change in speed. Tries 0/20 If the initial speed is, instead, twice as great, and the car experiences the same force during...

A truck of mass 9M is moving at a speed v = 15 km/h when it collides head-on with a parked car of mass M. Spring mounted bumpers ensure that the collision is essentially elastic. Find the final velocities of each vehicle. Repeat for the case of the car moving at speed v= 15km/h and colliding with the stationary truck. What fraction of the incident vehicle’s kinetic energy is transferred in each case?

The car has a speed of 100 km/h at A and 50 km/h at C. The
path distance from A to C is 120m. The total acceleration of the
car at A is 3 m/s^(2). The car has a constant tangential
acceleration.
1) determine the radius of curvature of the road at A.
2) determine the total acceleration at C.
